Pregnancy Due Date Calculator

Absolutely agree about "taking Charge" its amazing and don't let the book's size daunt you, only a small section is needed to teach pregnancy avoidance and achievement there is just lots of extra info on everything from how to time for a specific gender to infertility options including taking Mucinex, who knew!

I highly recommend 'Taking Charge of Your Fertility" by Toni Weschler as well. For a year, we've used the information learned in this book to prevent a pregnancy and have just succeeded in conceiving on our first attempt. Because I know my date of conception, I know the due date listed in this web site is off by two days.
Happy pregnancy to all!

This is only accurate if you have a 28 day cycle and ovulate on day 14. It's more accurate to figure out when you ovulate. Of course, that's too late after the fact but for those who aren't pregnant yet, get a book called "Taking Charge of Your Fertility." Otherwise, the only semi-accurate way to get a due date is a dating ultrasound early (first 12 weeks) in your pregnancy.

Don't forget that two week "flex" time.

This is completely inaccurate as I have a longer cycle and cysts which cause me to miss cycles at times... This says my due date is March 1, 2010 but my dr edd is April 12. More than likely, my due date is closer to April 27th as pregnancies are actually on average 42 weeks
