Fell on my butt, 32 weeks

I'm sure all is fine, but my cousin is freaking me out and making me second guess myself. I fell coming off my front deck this morning, I slipped on wet grass and landed pretty hard on my butt/leg. I haven't noticed any change in baby's movement and don't feel any pain or anything but she is insisting that I go to the emergency room or labor & delivery to get checked in case the placenta detached. I don't even know what that would feel like, but I feel like it would hurt and I feel fine. Any advice? Would you go to the doctor for something like that?
