Pregnancy Calculator

The pregnancy calculator will tell you when your due date is, and now that you are pregnant, that is something you would really want to know. On the first visit to your doctor he/she will confirm that you are pregnant and calculate your pregnancy due date.

The pregnancy calculator is simple and easy. The standard method of calculating your due date is to add 280 days to the first day of your last menstrual period, or LMP.

How this concept works
The 280-day cycle works on the typical 266-day gestation period plus 14 days, which would be the time from when you had your first day of your period, until the time when you would have more than likely ovulated. So you see how this is not exact science. The pregnancy calculator assumes that you have ovulated exactly 14 days after you started your period and also assumes the conception was done on that day.

There are other methods of calculating your due date of course, if you had been keeping track of your basal body temperature, thus knowing exactly when you had ovulated, had intercourse and fallen pregnant. If you know this exact date for sure, then you would simply add the 266-day typical gestation period, and you would have your due date.

Unfortunately there is no exact or perfect way of determining when your little bundle of joy will arrive. One thing you can be sure of is this: Your pregnancy may seem like a long time at the beginning, but it will arrive sooner than what you think.
