ER today

Well today didn't start out very well. I woke up around 5:40 and went to the bathroom only to find a pretty good amount of bleeding. Luckily, Joel walked in the door at that moment, and we went to the ER down the road. We got right in becausr that hospital is so small and never busy. The doctor checked me and said i was still closed up and seemed ok, and they also located baby's heartbeat. My main concern now is that they said it was around 120, when on Monday's Dr. visit they said it was around 150. So now i'm home, waiting for my doctor to call me back to see if she wants to see me today as well, or not. I really hope she does want to see me because i'd really like to have an u/s done to maybe determine where the bleeding came from, since that is abnormal at 13 weeks.
It's the scariest thing to not know what is happening to your baby. On the good side though, when they were trying to find the heartbeat, they kept having to move around because the little bugger moved away from the doppler every 15 seconds or so. This is definitely Joel's baby...difficult as ever. Well it's almsot 9am so my doc should be in soon...here's hoping...
