Since my due date is November-5-2009 what is the exact date I got pregnant?

The last time you had unprotected sex before knowing you were pregnant.

Go back 42 weeks and still that wouldonnly be an estimate!

Yep, you can only estimate, because all women are different each pregnancy, so unless you know, there is really no precise way to tell.

Why does it matter?

If you're wondering who the father is and that's why you're asking, you'll have to wait until the baby is born, get a DNA test.

We don't know when you ovulated, therefore we can't tell you the exact date you got pregnant.

Good luck.

Ooh Alt, I love your bluntness.

If that really is the case, you should sign up for the Maury Show! :)

Here is a site that I think will help you.
