You can use the chart above to figure out how the weeks of pregnancy correspond to months. Note that you're not technically one month pregnant until after 4 weeks have passed, for example. But you are "in your first month" during the first 4 weeks and "in month nine" during the last 4 weeks.
Actually, in a typical year, February is the only month that's four weeks or 28 days long. All others are either 30 or 31 days. On average, a month is 4. And that's why some months in the chart are four weeks long and some are five weeks long. Forty weeks is actually a little more than 9 months.
For example, if your last period started on January 1, your due date would be October 8. So that's more like nine months and one week or even longer if you go past your due date. There's no official definition, but each trimester is generally considered to be about three months long. At BabyCenter, you reach the second trimester the day you turn 14 weeks pregnant.
The third starts the day you turn 28 weeks pregnant. Because it's the easiest date to pinpoint. Many women don't know the day they ovulated. So doctors and midwives start counting pregnancy from the first day of your last menstrual period LMPwhich is usually about two weeks before you ovulate. By the way, even if you know the day you had sex that resulted in pregnancy, that may not be the day you conceived : Sperm can linger in your uterus for up to five days waiting for an egg to be released so they can fertilize it.
Your provider counts days 40 weeks from the first day of your LMP to determine your due date. Only 5 percent of babies are born on their due date. You're just as likely to deliver any time during the two weeks before or after that day.
Your baby is considered full term between 39 and 41 weeks. Note: Not everyone ovulates exactly two weeks after their LMP, so your due date may be adjusted if an early ultrasound indicates that your baby is more or less developed than expected.

Jukic AM et al. Length of human pregnancy and contributors to its natural variation. Human Reproduction 28 10 This is called her background risk. This fact sheet talks about the critical periods of development and types of birth defects that can result from exposures at different stages of pregnancy. This information should not take the place of medical care and advice from your health care provider. During these timesthe body can be very sensitive to damage caused by medications, alcohol or other harmful exposures.
Yes, the risk depends on what body part is developing at the time of exposure. Once a body part has formed, it is no longer at risk to develop major birth defects, but some exposures could still affect its growth and function.
The chart on the next page shows the critical periods of development for different parts of the body. The chart starts from the time of conception when the egg and sperm join.
This day is usually two weeks before a baby is conceived. For example, 12 gestational weeks since the day of your last period is the same as 10 fetal weeks since the first day of conception.
The dark bars on the chart show when each part is most sensitive to harmful exposures and at risk for major birth defects. Heart defects, spina bifida, and clubfeet are examples of major birth defects. The lightly shaded bars show periods when the body parts are still at risk to develop minor birth defects and functional defects. Minor birth defects can also be variations of normal development. Wide-set eyes and large ears are examples of minor birth defects.
Both major and minor birth defects are physical or structural changes. Intellectual disability and hearing loss are both examples of functional defects.
The chart also shows the location of the most common birth defects that can occur during each week. This is the same as 5 to 14 gestational weeks weeks since the first day of your last period. This is also referred to as the first trimester. Minor defects and functional defects including those affecting the brain are also able to occur later in pregnancy.
What is the greatest risk from a harmful exposure during very early pregnancy? Harmful exposures during very early pregnancy have the greatest risk of causing miscarriage.
A fertilized egg divides and attaches to the inside of the uterus during the first two weeks of embryo development. Very harmful exposures during this period first four weeks after the first day of your last period may interfere with the attachment of the embryo to the uterus.
Harmful exposures during this time can also damage all or most of the cells of the growing embryo. Problems with uterine attachment and severe cell damage can both result in a miscarriage.Use this calculator by plugging in either the date of your last menstrual cycle or the date of conception.
That's it! The pregnancy calculator will do the rest! There are several ways. If you happen to know the day you conceived, you can count 38 weeks from that day to find your due date. Human gestation takes about 38 weeks. But very few expectant moms know exactly when they conceived.

The most common way to calculate your pregnancy due date is by counting 40 weeks from the first day of your last menstrual period LMP. And that's how most healthcare providers do it. If your menstrual cycle length is the average length day cycleyour menstrual cycle probably started about two weeks before you conceived.
This explains why pregnancies are said to last 40 weeks instead of 38 weeks. This method doesn't take into account how long your menstrual cycle actually is or when you think you might have conceived.

Note: Again, you don't necessarily conceive on the day you have sex. If you had a Day 5 embryo transfer, count days from your transfer date.
If you had a Day 3 embryo transfer, count days. Your healthcare provider might revise your due date if your baby is measured during a first trimester ultrasound scan and found to be much bigger or smaller than expected for gestational age.
This is more likely to happen if you have an irregular menstrual cycle length that makes it hard to pinpoint the date of conception.

Methods for Estimating the Due date. American College of Obstetricians and Gynecologists.Last Updated on March 13, If you are an expecting mother, it is natural to have a growing anxiousness about your pregnancy.
There is a tendency among pregnant mothers to constantly track time — to determine the stage they have reached in their pregnancy and the time left for them to deliver the baby. While doing so, many women tend to get confused about the mathematics involved in calculating the gestational age or the due date, and the various nomenclatures used in terms of months, weeks, and trimesters.
This article emulates the fundamental concepts behind these calculations. A complete full-term pregnancy is usually considered as 40 weeks and the estimated date of confinement EDC or estimated due date EDD is calculated from the date of the last menstrual period LMP. In a full-term delivery, the baby is usually born around the time of the EDC. The ovulation period during which fertilisation happens typically falls two weeks after the menstrual cycle. Many people do not know the exact date of conception but mostly remember the date of their last menstrual period.
The time period of forty weeks is added to the LMP to get a tentative due date. During the first two weeks after LMP, you may just be ovulating and getting ready for fertilisation. However, the week time period added to LMP accounts for these non-pregnant time periods. Additionally, this calculation is based on the assumption that your menstrual cycle occurs once every 28 days. According to experts, full-term pregnancy is for 40 weeks. This is the basis on which the due date is also calculated.
However, any baby that crosses 39 weeks in the womb is considered to have finished the full term and attained complete growth inside the mother.
Delivery happens anywhere between the 39 th week and the 41 st week. The entire pregnancy period is divided into three trimesters of three months each.
The first three months of pregnancy come under the first trimester, the fourth to sixth months of pregnancy form the second trimesterand the seventh to ninth month form the last trimester of pregnancy. Usually, each trimester is characterised by some specific changes, and this categorisation helps in understanding the pregnancy better.
Each trimester roughly consists of 13 to 14 weeks. However, the accepted way of dividing the trimester is to consider week 1 to 13 as the first trimester13 to 27 as the second, and 28 to delivery as the third. The last trimester has an additional one week, compared to the other two trimesters. Different people choose to calculate the stage of pregnancy in different ways. Some people like to address it in terms of the number of months, while some others prefer to address it on the basis of trimesters.
Doctors usually calculate the pregnancy with the number of weeks, as they check the developmental milestones on a weekly basis. Expecting mothers usually find it confusing to choose a method of quantification and face difficulty in arriving at the exact number. The following chart can be very helpful in understanding the correlation between the weeks and their corresponding months of pregnancy.Most pregnancies last around 40 weeks or 38 weeks from conceptionso typically the best way to estimate your due date is to count 40 weeks, or days, from the first day of your last menstrual period LMP.
Another way to do it is to subtract three months from the first day of your last period and add seven days.
So if your last period started on April 11, you'd count back three months to January 11 and then add seven days, which means your due date would be January Calculating your due date based on the first day of your last period works well for women who have a relatively regular menstrual cycle.
But if your cycle is irregular, the LMP method may not work for you. Because a reliable estimated date of delivery EDD is important, you and your practitioner can use your conception date instead if you remember it.
Just add days to get your estimated due date. If you are part of the growing tribe of IVF moms, you can calculate your due date more precisely using your IVF transfer date. An early ultrasound, which can more accurately date the pregnancy. Just be aware, however, that not all women get an early ultrasound. Your fundal height, which is the measurement from your pubic bone to the top of your uterus, is checked by your practitioner at each prenatal visit and helps confirm your due date.
Whether you're trying to avoid being very pregnant in the middle of summer or are a teacher who wants to maximize time off with your little one, you can try to time when you conceive in order to "plan" your due date.
But even if you're one of the lucky ones who's able to get pregnant when she really wants to, just remember that you probably won't be able to map out exactly when you'll give birth to the day or even the week or month! It may be that your periods are irregular and your early ultrasound dating was off, or that your first ultrasound was in the second trimester.

The World Health Organization defines a normal pregnancy term to last between 37 and 47 weeks. During a person's first OB-GYN visit, the doctor will usually provide an estimated date based on a sonogram at which the child will be born, or due date. Alternatively, the due date can also be estimated based on a person's last menstrual period. While the due date can be estimated, the actual length of a pregnancy depends on various factors including age, length of previous pregnancies, and weight of the mother at birth.
Pregnancy can be detected either by using pregnancy tests, or by the woman herself noticing a number of symptoms including a missed menstrual period, increased basal body temperature, fatigue, nausea, and increased frequency of urination.
Pregnancy tests involve detection of hormones that serve as biomarkers for pregnancy and include clinical blood or urine tests that can detect pregnancy from six to eight days after fertilization. While clinical blood tests are more accurate, and can detect exact amounts of the hormone hCG which is only present during pregnancy earlier and in smaller quantities, they take more time to evaluate and are more expensive than home pregnancy urine tests.
It is also possible to get a clinical urine test, but these are not necessarily more accurate than a home pregnancy test, and can potentially be more costly. There are a number of factors that need to be considered during pregnancy, many of which are highly dependent on the individual's situation, such as medication, weight gain, exercise and nutrition.
Taking certain medications during pregnancy can have lasting effects on the fetus. In the U. Drugs that have positive benefit for the mother with low risk to the fetus are classified as category A, while drugs with proven, significant fetal risks that outweigh potential benefits to the mother are classified a category X. A person that is pregnant should consult their doctor regarding any medications they plan to use during their pregnancy.
Weight gain is a largely inevitable and necessary aspect of pregnancy that varies between people. It affects many aspects of fetal development such as the weight of the baby, the placenta, extra circulatory fluid, and its fat and protein stores.
Weight management merits consideration because insufficient or excessive weight gain can have negative effects for both mother and fetus including the need for cesarean section C-section and gestational hypertension. While the values vary between women, the Institute of Medicine recommends an overall pregnancy weight gain of pounds for women who are considered "normal" weight BMI Studies indicate that aerobic exercise during pregnancy helps to improve or maintain physical fitness as well as possibly decreasing the risk of C-section.
Although it varies between women, regular aerobic and strength-conditioning exercise are often recommended for pregnant women, and women who exercised regularly before pregnancy, who have uncomplicated pregnancies, should be able to continue high intensity exercise programs.
Nevertheless, caution is advised, and a pregnant woman should consult their doctor if any of the following symptoms present: vaginal bleeding, shortness of breath, dizziness, headache, calf pain or swelling, amniotic fluid leakage, decreased fetal movement, preterm labor, muscle weakness, or chest pain.
Nutrition during pregnancy is particularly important for the health of the mother and baby. Pregnancy requires different nutritional considerations than a person would have in a non-pregnant state, due to increased energy and specific micronutrient requirements. Certain vitamins such as Vitamin B9, also known as folic acid, can help decrease the risk of certain defects, while other nutrients such as DHA omega-3 that is necessary for proper brain and retinal development cannot be produced efficiently by infants, and can only be obtained through the placenta during pregnancy, or in breast milk after birth.
