I really just don't know how I'm suppose to feel right now. I'm at a complete loss. I went in yesterday to be able to hear my baby's heartbeat and I had been looking forward to this appointment. They couldn't find the heartbeat so I had to get an ultrasound and they find out I'm only measuring 6 weeks 5 days when I'm suppose to be at 10 weeks. They told me I could be off on my dates but I was tracking my periods and they also told me it could be a miscarriage. Of course they couldn't confirm it for sure so now I have to go back in 10 days for another ultrasound but from the way they were talking to me it sounds like a miscarriage. I don't know how to feel or what to do. I don't feel pregnant anymore... I feel like it's my fault. I've been crying on and off. This is going to be an agonizing 10 days. I'm trying to live life like normal but I really just want to stay in bed and sleep.
