How To Determine The Paternity Of The Fetus?

Well I made a mistake, I cant remember when I started my period. It was either the last couple days of July for the first couple days of August. So I slept with guy 1 on or between August forth + 7. We have been on and off for 2 years. We got in a fight I messed up. I slept with Guy 2 on August 16th. Got emergency contraception August 20th. Slept with Guy One August 22nd 24 26. I am now pregnant. Got an ultrasound too early to tell. I am really scared and I don t know when I conceived. Any advice would help ease my mind

Hi Welcome to HEALTHCARE MAGIC..

I have gone through your query and can understand your concern.
An ultrasound report would tell you about age of foetus in weeks.
As you said that You had your period on last few days of july or first days of august. So your conceiving date should be around 10th to 20th august.
Other method that determine the paternity of the fetus
1.DNA paternity testing is most advanced and accurate technology to determine parentage. More DNA paternity test can reveal the father of the unborn child also
2. Other methods including ABO blood group typing, analysis of various other proteins and enzymes, or using human leukocyte antigen antigens

Hope this information helps
