During my seperation with my bf I slept with a friend. My last period was Oct 24th, 2017 - Oct 27th. I had sex with the friend onceon Oct 29th. My bf and I ended up working things out and were back together around the 1st week of november and during the first two weeks back together we were having sex almost every couple of days. I been tracking my period for years and usually have a 30 day cycle, so my app says I would of ovulated around Nov 8th ish. I am 26 weeks pregnant with a Due date of Aug 2nd which means I concieved on Nov 9th. just trying to make sure that my bf is indeed the father of my child. I know sprem can live a few days but I dont think it can live from oct 29th until nov 9th when I ovulated
