My last period started on 22/11. I have been having unprotected sex w my BF regularly and consistently. My cycles are fairly regular 28/29 day cycles.
My estimated fertile window was 2/12 to 8/12 and I had sex w BF most of those days.
I had sex w a colleage (I know, I'm a silly girl) without protection drunkenly after our Xmas party on day 22 or 23 (it was after midnight) of my cycle (13/14 December). I took the MAP.
I just had a positive test on what would be day 28 of my cycle. I'm a bit frazzled and am seeing doc on Monday. Is there any significant chance it could be colleague's baby? I think the dates work out that it is more likely BFs. Any advice?
