Using the Pregnancy Date Calculator
Enter the date of your last menstrual period and the number of days in your menstrual cycle into the pregnancy calculator, and click on the Calculate button. Other calculations are optional - use them when needed.
On average, there are 28 days in a menstrual cycle, but it can last from as little as 22 to as many as 44 days. The Pregnancy Calculator takes your menstrual cycle into account when calculating the due date and the conception date.
Also, the Pregnancy Calculator needs the number of days in your menstrual cycle when calculating the likely conception date from the given due date.
Note: A woman can usually get pregnant during a period of 5 days each month, which is when ovulation is occurring. Typically, ovulation takes place between 12 to 16 days before your menstrual period starts. However, since sperm is able to live for 3 to 5 days within a woman's body, that makes it possible to still become pregnant even during the several days leading up to the egg's release (i.e. ovulation).
The above calculations are mathematical estimates and should not be considered infallible. If you do find any glaring errors, please don't hesitate to contact us.
