OK I have 2 questions....First what does it mean when I conceived? Does that mean I got pregnant on that day? The reason i am asking this is because I recently found out that I was pregnant...I don't remember when my last period was..I am pretty sure it was aroud Halloween of 2006..but I can not guarantee that! I went for an ultrasound and i was told that I am 17 weeks and 2 days..so when I counted back on my calendar it landed on November 5/2006. Now I was told that i conceived around the 18th of November. The only person I had been with up until November 21 was my ex..But on that day I slept with another guy..Now i am scared of who the father may be. What is the accuracy on an ultrasound and who do you think would be the father?
I believe the ultrasound is related to fetus development. They then add two weeks for the 14 day average between the first day of your period and ovulation.
How long are your cycles normally? Take that number and subtract 14. Add the result to the first day of your last period. This is the conception day. Anyone you had sex with on that day, the day after, or within three days before could be the father.
