So. I had sex with guy 1 on April 18th 2am. Then sex with Guy 2 on April 25th12am and 2am, 29th, May 1st May 3rd. Conception Date 27th April - Doctor says. On June 7th Doc said I'm 8 weeks Crown Rump 1.6cm
June 12th Doc says 8w4d Crown Rump 2.04cm. Since the beginning of January I've been irregular.. cycle would come late but it would come.. like it shifted foward days at times.. my last cycle. . Not sure if it was end of march or in april. Also took pregnancy test on April 23rd and 27th. Both said Not pregnant. So which guy is most likely to have gotten me pregnant?
