So, I'm 18weeks and this morning I went to see my dog (shes with my parents for my pregnancy) she's about 70lbs now. She was too excited and ran across the room and used my stomach as a cushion to bounce off of. She hit the side where the baby is ALWAYS at. Now he's not moving and I have a lot of pressure like I have the need to poop. Should I be concerned or go to the hospital?
