I got an ultrasound on July 9 that said I was ten weeks. Which goes back to April 29. My due date was Feb 3. I have been using that ever since. I always kept track of my periods and my lmp was April 4 to the 13. But using those would make my due date Jan 9. Which is way off.? When would my conception be from going off the ultrasound. Would it be April 29? Ten weeks before that ultrasound I'm co confused. Any help would be appreciated

The best guess is a four week window for conception, its NOT medically or scientifically possible at this day and time to get closer than that... if the exact date matters so you can know who the father was then a DNA test is the only way to know.

The only way to know an exact date is if that was the only day you ever had sex before finding out you were pregnant..

All these tests can do is allow them to make educated guesses... and guesses are inexact by nature.

Well I mean I know for a fact my period was April 4 -13. But that would make my due date Jan 8. My ultrasound says Feb 3

Well I mean I know for a fact my period was April 4 -13. But that would make my due date Jan 8. My ultrasound says Feb 3THe date of your period means nothing... some women conceive while having their period.

THe date of your period means nothing....some women concieve while having their period.

Thank you for your help. I appreciate it.
