Anyone else experience this?

Kimber

I am currently 35w6d pregnant and have been waking up to stomach tigthening all night. It doesn't hurt and can't tell if they are BH or just her moving towards the front of my belly. Also had to get up and take a bath because of charlie horse like feeling in upper/inner thigh and hip pain. Should I call or go in? Maybe she is flipping? She is also being extremely active.
