DUE DATE/CONCEPTION/OVULATION

[melmoms]

I've had two ultrasounds since I found out I was pregnant. The doctors have both said that my due date is Oct. 4th which comes from my LMP Dec. 28th and the two ultrasounds. Now the question I have is if I ovulated late would it affect the due date because all the conception calculators I've used and all the other types of calculators puts my most fertile days around the middle of Jan. (from about the 6-16th) on average. But the thing is I had sex with 3 different guys with 2 of them being in the early weeks of Jan. The third I had sex with on Jan 25th. I just want to know whether oit is possible to differenciate whether it is one of the two men earlier or the Jan 25th guy.

the actual date of conception is 2 weeks later than what they say. they say the first day of a pregnancy is the last day of your lmp. it's most likely one of the first 2 guys but u/s's can be off by 1-3 weeks. so the ONLY way to know who the father is is to have a paternity test done once the baby is born.
