I originally was going to announce our pregnancy on Valentine's Day where I will be 13.2 weeks but now I'm thinking I may wait till February 28th where I will be 15.2 weeks. I just want to make sure I hear my baby's heartbeat one more time before I announce. I heard my baby's heartbeat at 7.5 weeks and it was 143bpm and at 11.2 weeks and it was 160bpm. What should I do. Wait till 15 weeks or just go ahead and announce at 13 weeks........
