BH/Cramps or poop feeling?

So it’s been a few years since I have felt cramp like feeling that like poop feeling. (When I was in high school on my period)

I’m 35 weeks pregnant and I can’t tell if it’s BH/small contractions or just needing to #2. 😂

I haven’t had cramps or anything when I started on bc or when I got off for a year to regulate my period before getting pregnant.

I’ve had small on and off cramp like feeling that made me feel like I had to go #2. But I don’t need to after the pain goes away.

First pregnancy. Sorry if it’s a dumb question! Can someone tell me if it’s BH/contraction feeling?
