... And again it happened. I took another pill. I got a"period" on Dec. 14. Then another one on the 29. Me and the bf broke up and I went back to my husband. We are TTC and started on the Jan. 14th. I haven't had a period since the 29th. Would I know by now if I was pregnant by my ex bf? Its been a month. I take tests but they are negative. If I eventually get a positive would it be my husbands? Since Me and my ex split on the 13 of Dec. And my husband and me ttc on the 14th of Jan? The pillB got my cycle messed up and I don't wanna be that 20% chance of the pill not working and have a kid with my ex bf
