I had sex on a supposed ovulation day 08/13 with guy A. And sex with guy B the rest of the month. Got what I believed to be my period on 08/26, and continued sex with guy B. Took a preg test on 09/26 and it came up positive. Went to doc 10/03 and was about 4.5 weeks pregnant. Is there a possibility the dating is wrong and I got preg from guy a? My doc told me however I conceived 09/15 or around there. Is he basing the conception date off of my LMP? Or what
