Hi, I m nearly 18 wks pregnant. My last period started on the 17th July and i average a 32 day cycle. I had unprotected sex on the 18th day of my cycle which works out as my ovulation day, however 10 days later, (3 days before i was due on) I got very drunk on a night out and a male friend took me home, I can t remember what happened and haven t seen him since. I realised 6 days after that night i was 3 days late on my period so did a test which came up positive straight away. I m pretty sure from what I ve looked into that the guy i slept with on my ovulation is the father however im having a problem getting this other person out of my head!! what do you think?
