My last period start date was March 26, 2009, so I was expecting my period to start on the 26th of April. It is now 10 days later and I just took a pregnancy test and its POSITIVE!!

So my question is: Approx when would I have conceived and how far long in my pregnancy would I be now?

Far as I know, u mite have conceived between 6th - 12th,,
M in the same cycle, 2 days apart,,

Oh,, congratulations...

A doctor figures your due date as if the pregnancy began when your last period started. That way, if you are "pregnant" for 40 weeks, it's time to give birth.

You most likely conceived 14 days after March 26th.
