My last period came on Sept. 19, 2007 and I had unprotected sex on Sept. 22 my period didn't go off until Sept. 26, 2007 and I had unprotected sex then I'm currently pregnant and I was just wondering out of the 2 days of unprotected sex when could I have possibly conceived.

Let's see, you started your period Sept 19 and stopped on Sept 26? Is that right?

Well then, you possibly conceived around the 3rd, 4th or 5th of October.

While it is possible, it is rare that a woman gets pregnant on her period. Could you have gotten pregnant around the first week of September?

I'm sure that doctor would be able to pinpoint that one for you... But is the EXACT date that important to you? I would pick one and go with that..

You could have conceived during days you had protected sex.
