Using both the date of your last period and the length of your regular cycle, or exact date of conception, our Due Date Calculator will quickly work out your estimated due date, tailoring it accordingly for longer, shorter, and average cycle lengths. Luckily, our Due Date Calculator can help. Unless you can pinpoint exactly what point of your ovulation cycle you were in at the time of fertilization, it’s difficult to know how far along you are and what date you’ll meet your baby. That means that simply estimating nine months from the day you take a pregnancy test isn’t going to calculate your due date, and, even so, factoring in a few weeks here and there for ovulation won’t either.

Many won’t be aware of their pregnancy until their first missed period, and by that time they could be up to five weeks in.

Most expectant mothers don’t realize that both menstrual and ovulation periods count as the first two weeks of pregnancy. These are probable conception dates based on an average cycle of 28 days. estimates that first babies come on average 41 weeks, 2 days subsequent babies around 40 weeks, 5 daysĪll that said, here's a fairly comprehensive, queer-friendly, IVF-inclusive due date calculator.While it’s true that most pregnancies last 40 weeks, there are other factors at play which will determine your due date. Conception Calculator will estimate probable conception dates.

first babies come a little later than subsequent births.those with cycles longer or shorter than 28 days do not ovulate on the 14th day Wood's method adjusts based on average cycle length, bringing the whole pregnancy forward or back a bit for accuracy.The Wood's Method, sometimes called Nicol's Rule, is based on research and reflects the following important points: And if your cycle is a lot shorter or a lot longer, your dates will be off even further. Though this is the average, most of us have cycles that tend to be a little shorter or a little longer, and the proliferative phase (the phase preparing for ovulation) is the one that changes with cycle length, so this throws off the due date. This calculation is calculated from the first day of your last period, based upon a 28-day cycle and the assumption everyone ovulates on day 14.It's based on the 'research' of Harmanni Boerhaave, a botanist, not a birth professional or even a human biologist, who came up with the 40 weeks thing when he noticed that pregnancies in the Bible are described as being about 10 lunar months, which is 280 days.Those fun little due date wheels usually follow Naegele's Rule. Most doctors use Naegele's Rule, which is where we get the 40 week due date. How do they come up with these numbers, anyway?
