Count back 13 weeks and 1 day from Sept 25th. That should give you the first day of your last period or close to it since 40 weeks of pregnancy includes the week you have your last period though that seems funny, and then count approximately 14 days after that since MOSt, not all, women ovulate 14 days after the 1st day of their last period.

The ultra sound tech should have told you that dates using those can be off either direction by about 2 weeks. Ask your doctor ...they should be able to tell you within a few weeks of when you most likely concieved. Again its all gonna be a rough estimate. Congrats and good luck with the pregnancy!

Try this web site. It will tell you when you conceived and when you start each new week. I love this site. It also will show you what to expect each week and show ultrasound pictures at each week. Also has an awesome belly gallery to show you what other women look like at each week. I love it. Congrats.

I'm guessing right around July 9.
But I would ask your doctor. Don't worry, they get that question all the time.
And conception date is ALWAYS an estimate.

I don't know but it takes about 10 hours for the sperm to swim through your vagina and find the egg. So I believe it takes about 2-3 days.
