Getting Started

Just found out you're pregnant? Congrats! Now, use our due date calculator to figure out when baby will arrive. Enter the first day of your last menstrual period and hit calculate to find your expected due date as well as when each trimester will begin. Our pregnancy due date calculator (and all other estimations of baby due date) is based on an average menstrual cycle of 28 days. Ovulation occurs about two weeks into your cycle (meaning, two weeks after your period starts), and it’s the few days before and after when you are most fertile and conception occurs. For those two weeks after your period, you aren’t actually pregnant, but they are included when calculating the weeks of pregnancy and your due date for the sake of simplicity -- the easiest part of your premenstrual cycle to recognize is your period, of course. Keep in mind, though, that the pregnancy due date our calculator gives you is an estimate -- there’s no way to know exactly when you conceived, and even if there were, there’s certainly no guarantee that your little boy or girl will actually decide to emerge exactly when he or she is expected. Scroll down for more information on conception and early pregnancy. Good luck, and congrats again!

Q: What tests and screenings will I need throughout my pregnancy, and when?
A:

All those pee cups and needle sticks definitely start blurring together pretty fast. At your first checkup, the doc will take blood for a long list of screenings and to confirm your pregnancy. You'll also have a urine test and pap smear, and possibly an ultrasound. Between weeks ten and twelve, you may opt to have chorionic villus sampling...
