Pregnancy Timeline: Conception Dates After Menstruation - Expert Advice

Question
After reading so much information about when you can ovulate,  I was trying to figure out if my last menstrual cycle started on August 26, 2006, is there anyway that i could have gotten pregnant the night before i got it, or 2 to 3 days after? Or would I have most likely conceived around September 9th?  I just need a little bit more reassurance... because i am having a little problem stressing out if my ex-boyfriend could be the father. And the last time I was with him was the night before I got my period.  Is there ANY possible way that i could have conceived then? Please if you could help me out? I would really appreciate it. I'm trying to get this off of my mind so I'm not stressed anymore.

Answer
Dear Kala,

OK - are you saying that you know that your LMP started on 8/26/06? If so, I'd calculate your due date at 6/3/07. Is that correct? Have you had an ultrasound to confirm a due date yet?

If those are correct dates so far, then your estimated conception date would be 9/10/06, based on a average menstrual cycle of 28 days.

I hope that information has helped answer your question. Please feel free to write again with any further questions.
