trying to figure out when I conceived and who the father is. My Ex boyfriend and I Had sex March 4th-6th, 11th-13th, 18th-20th, 24th-28th. We pretty much broke up the next day. Then April 1st-3rd I had sex with another guy. Took a pregnancy test April 6th with first response and it was faint positive..also took a digital clear blue and it read "Pregnant". Went to clinic to take their urine test on the 8th of april two days later...it was positive. Then went back for ultrasound May 3rd and they said 7wks 2days. I went to a dating scan the following month on June 8th that put me at 13wks1day, which is 5 days earlier than the US on May 3rd, putting my due date at December 13th. I calculated my conception date from my due date which said I conceived around March 22nd. However, I don't know when I ovulated due to irregular periods. Also, not sure which scan is more accurate..so its just a mess. I don't know if I got pregnant with the other guy on April 1st-3rd or if it was from the sex in march with my ex.
