Understanding Post-Abortion Pregnancy Test & Ultrasound Results

Question
ok lets start from the beginning i had an abortion on the 6th of may i started my birth control pills the same day! i took the pills up to the day i started my period on may 25th. On june 25th i took a pregnancy test and it was positive! i went to the doctor to have an ultrasound on june 28th they saw no baby or sac only a corpus lumeom cyst(how ever you spell it). i went back every 2 days until july 9th and this day they saw the sac and a heart beat my last period was 6.4 days ago and the baby measured 6.1 days i was told that my conception date was approximatly 4.1 days ago to 4.4 days ago saying i ovaluated any where from june 5 to june 10th so there for would have gotten pregnant during these times. My only concern is that i had sex with someone else besides my husband on may 22-24th.but i was on birth control then and on june 28th they saw no signs of life. i had sex with my husband may 31 through june 21st. my question is who is the childs father. i am pretty sure its my husband from what i told you above but want your expert opinion on this also. my first ultrasound at 6 weeks gave me a due date of march 1 y second at 20 weeks gave me a due date of feb 27 or 28th and my last gave me a due date of march 1 again.

Answer
Brittany,
Whew!! I think you are in the clear. According to all of the dates you gave me, you conceived somewhere between June 1 and 8. I would say it is immpossible to conceive and then have a period a week later. Unless it wasn't a regular period and were already pregnant, but then your ultrasound would give you completly different dates. I hope this helps! Good luck to you!
