Last night I slipped on ice and hit the back of my head really hard. Right after it happened, I was seeing double but that quickly went away. I was also slightly dizzy after I stood back up but that also went away fairly quick. About five minutes later, my jaws were very sore. I assume that was from tensing up. I was able to sleep a little last night. Went to bed about five hours after it happened. Also 17 weeks pregnant but not concerned anything is wrong with the baby since I fell backwards. Tail bone pretty sore too.
