How To Determine The Exact Date Of Conception?

I had sex with guy #1 on august 17th no protection. I started my period on august 19th. I ended my period on august 24th and had sex with guy #1 on that same day with no protection. One week later i had sex with guy #2 also no protection. I then had sex again with guy #2 on September 6th. Im not sure it guy #1 ejaculated inside of me, but im very sure guy #2 did ejaculated inside of me. On September 9th i checked if i was pregnant but it came out negative. On September 22nd i checked again and it came out positive. Who is the father of my baby?

Hi & Welcome to HCM.
I can understand your concern and the situation.
Guy#2 appears to be the father of your unborn baby.
Since you had unprotected sex with Guy#1 on August 1st but had your normal period from September 19th to 24th and unprotected sex again with the same guy on August 24 (which is a safe period), Guy#1 does not seem to be the father of your unborn baby.
Since you had unprotected sex with Guy#2 on 31st August and September 6th and having the first day of your last menstrual period on August 19th, the probable date of ovulation being September 2nd and the possible dates of conception being between August 29 to September 6th, hence Guy#2 appears to be the father of your unborn baby. However, the paternity test is advised for the confirmation of the biological father. Hope this will help you.
