My last menstrual period was Dec 8th, 2013. My periods are almost always exactly 28 days apart. I had one sexual partner Dec. 19th, which would have been 3-4 days before my ovulation and another partner on Dec 22nd, my ovulation date approximately...on Dec 28th I had cramping symptoms as well as very tender breasts. On Dec 30, one week before my period was due I got a positive pregnancy test. Can you please tell me your thoughts on who the father is likely to be? I know it's possible for both, but didn't think I would get a positive result so quickly of it was the 2nd mans. Thank you
