Please help me calm my nerves

So last night my husband had some guys over and he (hubs) got really drunk. Any way I went to bed long before them and when he came to bed he was kind of disoriented. At some point he was talking in his sleep and actually hit me pretty hard a couple of times in the low left side of my belly - not sure if it was his hand or elbow. Anyway - I haven't been feeling the baby move as much today and now I'm freaking out! 
Just FYI that is really what happened, I'm not trying to cover up a domestic violence situation or anything. Does anyone have any advice? Or has something similar happened to them?
