Okay so I'm 5w6d with my second child, I was spotting a little bit but not blood, it was more brownish. So my doctor had my blood work done to check my hcg levels and they were at 2,900 which was a little low..did them again a few days later and they are now up to 10,000 which she said is great!! I had an early internal ultrasound yesterday and she could see the fetus, and said the yolk sac and all that was there and it looked normal and good..she can't see the baby yet though so we're gonna do another ultrasound next week. She said for me being so early its normal to not be able to see the baby inside the yolk sac yet, but I see girls on here at 6 weeks already hearing their babies heartbeat.. Anybody have any input? Please help me ease my mind....
