Waiting Game

I had my first appointment on Tuesday and they took blood. And they still haven't gotten it back. We couldn't tell how far along I was because it was to early. So we are waiting for blood work. I'm assuming now I'm 5 weeks. We can't go off my last cycle because I haven't had one, I had a miscarriage at the end of July and got pregnant right away. I feel fine all normal pregnancy symptoms but I just want to know! Going crazy here!
