Okay ladies. My boyfriend and I are trying for my rainbow baby. I’ve been having spotting that I thought might be my period but it’s not like it normally is and I am three days late if it’s not. We were having sex this morning and there was ALOT of blood so i thought it finally came and still nothing. I’ve taken two pregnancy tests and they were both negative so I’m at a loss now. Any ideas as to what’s going on?
