Can Exact Day of Conception be calculated?

It is not easy to determine the exact date of conception as ovulation is a complex event in a woman’s body. Usually, women ovulate during the 11th to 21st days of their menstrual cycle and this is a broad period. Moreover, women do not track the ovulation by monitoring the cervical mucus along with their basal body temperature and if some women do this they might skip or forget by a day or more. To make it more complex, here is a fact that, conception can occur within a few hours of intercourse or can even take the time up to a week after intercourse. This is because a male sperm can survive up to 48 to 72 hrs in the female vagina.

How to calculate the date of Conception?

Same as the due date calculator, the reverse due date calculator will help in the determination of the date of conception. It uses just simple maths. In the case of a standard 28-day cycle, pregnancy is estimated to be 280 days or 40 weeks from the last menstrual period and 266 days or 38 weeks from the date of ovulation. Hence it is calculated by subtracting 266 days from your estimated due date. For example, if a woman has a due date of December 8th then December 8 – 8 days in December = 258th day i.e. November 30th. Now 258-30 days in November = 228 i.e. October 31st and so on till the last 14 days remain and this would come around march 15th.
