How do you calculate the day on which you got pregnant?

Answer 1

Your pregnancy is considered to have started on the first day of the cycle in which you got pregnant. Since most women have a 28-day cycle and they conceived around the 14th day, you are technically considered 2 weeks pregnant at the time of conception. Therefore, by the time you find out you are pregnant (you've noticed you missed your period, pregnancy test is positive) you are considered about 4 weeks pregnant. hope this is what you were looking for.

Answer 2

Do you mean how do they determine how far along you are? Pregnancy is 40 weeks long. It starts the day of conception. When you realize you have missed your period you are already 4 weeks along or maybe further depending on how quickly you realize you are late. Go back to the first day of your last period, and you probably ovulated 10-15 days after that, that is week 1, and that is how they figure how many weeks you are.

Answer 3

If you can remember the day of your last period, you count 14 days and that should be your conception date.

Answer 4

One way is to count 10 months after the end of the last period.

Answer 5

Answer 6

It's 40 weeks from the date of conception; plus or minus 2 weeks.

Answer 7
