pregnancy month calculator based on due date

This rule is based on a decades-old study that showed that first pregnancies tend to be slightly longer (an average of 288 days from LMP), and for subsequent pregnancies, the delivery date is an average of 283 days from LMP.

If you had a Day 3 embryo transfer, count 263 days.

If you had a Day 5 embryo transfer, count 261 days from your transfer date.

If you conceived through IVF, you can calculate your due date using your IVF transfer date.

Note: Again, you don't necessarily conceive on the day you have sex.

Just choose that calculation method from the pulldown above and put in your date.

If you do happen to know precisely when you conceived – say, if you were using an ovulation predictor kit or tracking your ovulation symptoms – you can calculate your pregnancy due date based on your conception date.

And women are more likely to know when their last period started than the day they ovulated.

But generally speaking, women typically ovulate about two weeks after their menstrual cycle starts.

This method doesn't take into account how long your menstrual cycle actually is or when you think you might have conceived.

This explains why pregnancies are said to last 40 weeks instead of 38 weeks.

If your menstrual cycle length is the average length (28-day cycle), your menstrual cycle probably started about two weeks before you 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.

So, without knowing the day of conception, how does anyone determine a due date?.

So, it could be up to five days after you have sex that you release an egg (ovulate) and it gets fertilized by a waiting sperm.

Sperm can live for up to five days inside your fallopian tubes.

Even if you only had sex once during your fertile period, you wouldn't conceive on that day unless you happen to be ovulating.

But very few expectant moms know exactly when they conceived.

If you happen to know the day you conceived, you can count 38 weeks from that day to find your due date.

There are several ways your due date is determined.

Enter the Average Length of Menstrual Cycles.

Enter the First Day of Your Last Menstrual Period.
