Contractions or movement?

Breanna

I’m a ftm so don’t mind me if I sound stupid 😳🤣

I’m 39 weeks + 6 days and my baby is pretty engaged in my pelvic from what my doctor says. Today I’m having this weird feeling in my pelvic, it kinda reminds me of a tightening & pulsating feeling, like when your muscle gets tight then releases, but it doesn’t hurt or anything just weird. I can’t really tell are these contractions or if its her moving around in my pelvic.
