I'm not worried as she said that it might just be too early for a heartbeat. I am supposed to do another beta draw in a few days to make sure my levels double. Since I had spotting, that was the main concern. The spotting is gone now, but I'm going to keep an eye on things for a while.
They also ruled out ectopic pregnancy since baby is in utero! I am going to just relax for the next few days until my blood draw.
