Welcome to your 37th week of pregnancy, and congratulations! The baby moves further into the pelvis. Make sure you are ready for the arrival of a new family member. At 38 weeks pregnant, you can find yourself spending the whole life peeing.
The pressure on your bladder is tremendous. Your baby is a fully functioning little human and your placenta is fully grown. Welcome to the week 39 of pregnancy! Your baby is full term, meaning that it is fully developed and is only waiting for the right time to make an entrance into the world.

But rest assured that plenty of moms-to-be go past their due date and everything turns out just fine. When a pregnancy lasts for 42 weeks or more it is referred to as a post-term pregnancy. By using some basic information about your last period and cycle length, our pregnancy calculator can help you work out your estimated due date EDD — aka when you might meet your baby.
Try using our EDD calculator now and then scroll down for more on how due dates and pregnancy are calculated, plus information on when you could have conceived and how far along you might be. More on those below, but when you know how far into your pregnancy you are, you can get a clearer idea of your expected date of delivery. This is another name for a due date, meaning your EDD is the approximate date when labor is expected to begin.
To track pregnancy and calculate a due date, doctors use gestational age. Gestation is how long a person is pregnant in weeks, and gestational age is measured from the last menstrual period LMP — the first day of your last period — to the current date in weeks. In general, pregnancies last anywhere from 38 to 42 weeks or around days. If a baby is born before 37 weeks, they are considered premature.
The other method of measurement is fetal age. While gestational age measures how far along a pregnancy is in weeks, fetal age is the actual age of the growing baby. To calculate this, you work out the amount of time from the date of conception which is around two weeks later than your LMP in a day cycle but varies depending on cycle length to the current date in weeks.
Charlsie Celestine , Flo board member, obstetrician, and gynecologist OB-GYN , explains. But some women can go beyond that to 41 weeks. Learn more about how you count pregnancy weeks here.
Celestine says, adding that this is usually done at your first appointment. If your cycle lasts longer, the estimated due date will likely be later.
If you have a shorter cycle, your due date may be earlier. Celestine, explaining how she tends to work out the due date in her patients. But an ultrasound scan in the first trimester is used to check that the dating based on the last menstrual period is correct. Celestine explains. I then compare that date to the result I would get from just using the LMP.
But for a greater-than-five-day difference, we use the ultrasound. Already had your first ultrasound scan? Then you can use our Due Date by Ultrasound Calculator.
The theories are as follows:. One theory on how to calculate due date, also using LMP, is the Mittendorf-Williams rule. This rule is based on a decades-old study that showed that first pregnancies tend to be slightly longer an average of days from LMP , and for subsequent pregnancies, the delivery date is an average of days from LMP.
The idea goes, however, that it can help predict due date in those who have irregular cycles. So, how does it work? In short, use this formula:. However, there is also minimal research on this and its effectiveness. To work it out …. If your cycle runs like clockwork, and you were having sex to get pregnant at a specific time, then you might have an inkling that conception happened on a certain date.
But Dr. Use our IVF Due Date Calculator to work out when you could be due. Usually, delivery happens within a week before or after. But there are many babies also born prematurely, [along with] medical reasons why you might need to be induced for labor early, so it really depends on the individual.
