Fell down stairs and SCARED

I'm trying to be rational about this ladies. I'm 7 weeks and a few days. I slipped walking downstairs on some matted carpet - feet went out from under me, and my butt landed on the third stair from the top. I haven't had any bleeding or discharge. What hurts is my foot and my arm that grabbed the railing. I'm freaking out that it's going to hurt the baby or initiate miscarriage. I've cried and cried. Has this or something similar happened to anyone else while pregnant? Am I overreacting?
