Finding the date of conception is very simple if you know the due date or if you have consulted a doctor. Subtract 266 days and you get it. The length of pregnancy is 280 days and you have to subtract 14 days to take into account the first two weeks before you ovulated. It is so simple. If you are in the habit of charting your menstrual cycle, you are better placed to calculate the date of conception. The matter of the fact is you know when you ovulated before you conceived. As you know, biologically the egg is fertilized within 24 hours and you can narrow it down and you are 99 percent sure of the date.
On the other hand, if you have no idea when you ovulated last before pregnancy, you have to cover a lot of ground making calculated guess. However, you can still find out the estimated date of conception. Firstly Start things objectively by marking the first day of your last menstrual period. Once you have done it, you can add elven days to the first day of your last period and you get the first possible day of conception. If you add ten more days to it, you get the possible ten days. See, now you have narrowed it down to a period of 10 days. Mind you, you can follow your instinct and intuition now because you are going to narrow it down further. Your body tells you something. Listen to the voice within and take every aspect into consideration before you narrow it down to the most possible date of conception. No doubt, practical and common sense play a role when you finally determine the conception date.
The funny side about this is you can sometimes narrow it down to the exact date, but sometimes you miss the exact day. Even if you miss the exact date of conception you will be very close to it. The margin of error is always there. The baby never arrive on the exact due date; it is born a little earlier or later!
Conception date calculator
The conception date calculator helps you calculate the pregnancy conception date and gives you the due date. The key date at the beginning of a pregnancy is the last date of your menstrual period which helps you find both date of conception and due date. Ovulation happens 14 days before your period is due, if at all you have an ideal 28-day menstrual cycle. And the conception happens from that day onwards. If your menstrual cycle is a bit longer, the ovulation happens a few days later, you baby arrives a few day after the estimated due date. On the other hand, if you menstrual cycle is shorter than 28 days, you ovulate early and the baby arrives a few days earlier than expected. For a woman with a regular period the conception usually occurs 11-21 days after the first day of the last menstrual period. The issue is most women do not know the exact date of conception and conception date is calculated from the first day of the last menstrual period. To be precise, the counting begins two weeks before the exact date of conception. Usually the length of pregnancy is counted as280 days or 40 weeks from the first day of the last period.
It is not right to assume that the date of conception and the date of intercourse are the same because the sperm can live inside your body for 5 days. You may get pregnant even if you make love 5 days before ovulation happens. The due date is calculated by adding 280 days to the date of conception. At the beginning of a pregnancy everything seems confusing and sometimes you may not be good at numbers. That is why we keep everything simple. What you just need to do is just type in the first day of your Last Menstrual Period and the average length of your menstrual cycle. Now Type in the details and find out conception date.
