DNA/CONCEPTION

[s_o22]

* i posted a question earlier, but had some of the info not all there*

I am 29 weeks pregnant, my due date is October 10, 2010. My last menstral period was Jan 6-Jan 10. i went to the doctor on Feb. 22, and she said i was 7 weeks pregnant. i had been with my boyfriend for three years, and had sex very frequently. we had sex Jan 1, 3, 8, 9, 10, 11, 12, 13th. (i was on my period a couple times we had sex.) We broke up, and i had sex with someone else around Jan. 20th. I asked my doctor if she was sure about the 7 weeks, adn she said yes, even though my period was not over until the 10th. i went to the doctor for an ultra sound around 21 weeks and the baby weighed about 1.3 lbs, and my due date has not changed. i just want some assurance, or some opinions on who the father would be. i know it is close to time, but i really believe and according to the doctor my first partner would be the father. i do not think that doctors could be that far off, becuase i thought it took about 10-14 days after sex to become pregnant, which if i went to the doctor feb. 22, and the doctor said im 7 weeks, there isnt a way it could be the second partners. right? im just afraid. any help would be appreciated.

they count the weeks from the 1st day of your last period, so 6th Jan. if you ovulated regularly and your period was more or less every 28 days, your time of conception would be around 14 days after the 6th Jan.. so the 20th Jan.

so that's my calculation, but obviously you'll be needing a DNA test. it would be wrong of you not to, for the child and both potential fathers.

Well put, sara - s_o22, it could be either man who is the father. Your most fertile time is mid-cycle, if you are regular, as sara says.

the only way you can be sure is to have a DNA when the baby is born im afraid.

[ummmm]

Yes...ovulation is 14 days before you period.
