I am currently 19weeks pregnant, my estimated due date is May 28, 2020. I found out I was pregnant on September 26, 2019 at my doctors office. In the month of August, I had sexual intercourse with 2 different men. One was on August 5th, for which I took an emergency contraceptive for on August 7th. The other incident was with another man on two different dates, one was August 24th & August 31st. I am irregular on cycles & the first day of my last menstrual period was on July 23rd, which lasted 4 days. My cycles tends to be about 40-45 days apart. If I were to go based off of my period tracking app, my fertile window was from August 19 to the 25th, ovulating on the 24th. But, because my periods are pretty irregular, I’m not sure if I want to trust my app all the way. Anyway, I was given an ultrasound during my appointment on September 26th & both the ultrasound tech & doctor explained to me that I was too early into my pregnancy to determine how many weeks I was & I was likely under 4 weeks because gestational sac was not visible. On October 5th, I had another ultrasound & she could estimate about 5 weeks pregnant. So my question after this long rant would be... who would likely be the father? Man 1 or 2? It’s been killing me since I knew I was pregnant. HELP, PLEASE!
