My LMP was November 06, 2016. Had protected sex with a condom with guy A on November 11, 2016 day 6. I was still on my period. Had unprotected sex with guy B several times (i hardly remember the dates) the rest of the cycle. However i got ovulation pains on November 22, 2016. I had what i thought was implantation spotting on December 7, 2016. My dating scan put my EDD to August 13, 2017. I had an ultrasound on January 11, 2017 and it put mw on 10weeks + 1day. I think the odds are in favour of guy B. What do you think? Thank you
