Pregnancy Calendar and Due Date Calculator. Calculate Based On: Last Period, Conception Date, Due Date. First Day of Last Menstrual Period*. Average.

Most pregnancies last around 40 weeks or 38 weeks from conception , so 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.

How to Calculate Your Pregnancy Due Date

Are you expecting? Use this pregnancy due date calculator to find out when your baby is due. Your health care provider will confirm the baby’s gestational age with a first trimester ultrasound.

Babies usually are born within weeks of their due date; only 4 out of babies arrive on that exact day. A term baby is a baby born between 37 and 41 weeks.

There are a number of different ways to calculate your due date, including:. Your due date is considered to be 40 weeks days after the first day of your last menstrual period or 38 weeks days after ovulation.

Because the human egg is capable of fertilization for only 12 to 24 hours after ovulation the date of ovulation may be taken as being the date of conception. However, ultrasound determination of the date of ovulation has the same imprecision as does the ultrasound estimate of the gestational age and, therefore, a precise date of conception cannot usually be determined as with in vitro fertilization.

In addition, although a woman is most likely to become pregnant if she has sex on the day of ovulation conception may also occur from live sperm still in her reproductive tract on the day of ovulation if she had sex for up to five days before ovulation [26,27]. The due date may be estimated by adding days 9 months and 7 days to the first day of the last menstrual period LMP. This is the method used by “pregnancy wheels”.

Usual number of days in your period: 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 Although most women understand the basics of the menstrual cycle, how babies are made, and the gestation process, it’s surprising how little we actually know about our own bodies and the reproductive process. Of course, thanks to expanding technological innovation, the medical community is learning more and more. But as a woman and a prospective mother, you could probably benefit from some targeted education on the subject.

But there’s a lot of information to sift through and you might not know where to get started, especially if you don’t fit the norm. So here is a basic guide that can help you understand your menstrual cycle, the process of conception and gestation, and how due dates are determined. If you’re looking for basic information that you can use as a springboard for questioning your gynecologist or seeking out more targeted texts, here are a few points you’ll want to be aware of.

The average menstrual cycle is 28 days and consists of four phases. It’s important to remember that every woman’s body is different, and unless you happen to be on some kind of hormone regulation such as the birth control pill it’s completely normal for your cycle to range anywhere from 21 to 35 days. For the sake of convenience, however, we’ll discuss a day cycle and how the menstrual phases land within that time frame.

Within your menstrual cycle, you’ll experience the following phases: menstrual, follicular, ovulation, and luteal, each with its own hallmarks. You’re almost certainly familiar with the menstruation phase already – it is more commonly referred to as the period and it makes up roughly the first week of every menstrual cycle.
