Blood test to confirm

Lynzey
Well, I went yesterday n got my blood work done and an U/S to confirm this pregnancy. My HCG levels were 2,730 and as long as they double by tomoro, I'll feel a little better knowing that's everything's ok. I'm still just super worried, as I don't want to go through another miscarriage, and I surely don't want to see my guy go through that again. I am a little worried, because I've read on here that many women can hear a heartbeat around the 5-6 week mark, and all we saw was a gestational sack. Has anyone else gone in for an early ultrasound n not heard the heartbeat, but gone on to have a healthy Lil baby?
