I'm preg with baby #2. Found out via ultrasound this morning that I am 5w5d preg. But the heartbeat was very hard to read. Should I be freaked out. My hcg levels are rising, 2400, 3700 and 11,000 today. I am a nervous wreck about the faint/ hard to read heartbeat. Anyone ever experience this and have a positive outcome? Please don't share horror stories
