Me and my girlfriend are in a relationship and really wanted a baby so we met a guy in a bar to donate some semen and we inserted it into me when we got home. Few weeks later found out I was pregnant and we were over joyed... But what I haven't told her is around about the same time I slept with my ex boyfriend so it could be his baby. I really want to tell her but she will never understand if the baby is his. I dont know what to do please HELP should I tell my girlfriend? Or does it not matter as its not her baby anyway?
