Using the Due Date Calculator

Enter the first day of your last period. If you don't know the exact date, calculate as close as possible. The calculator will show you your estimated date of ovulation and the expected due date of your baby.

Keep in mind that this is an estimate based on your last menstrual period and estimated date of conception. Always consult your physician or other health care professional concerning your due date.

As soon as you think you're pregnant, it's important that you contact your physician or other health care professional immediately.
