Is this preterm labor? 31 weeks.

I’m having period cramps and I thought it was because I needed to poop but I’ve been trying to go and nothing happens. I pooped 2 times earlier today so not sure what’s happening now. Sorry TMI. My back hurts and I’ve been laying down for the last 3 hours off and on. Trying to get comfortable. Baby girl has been super active all day. Not sure what is going on. I know the duh answer is to go and get checked. I just don’t want to look like a fool if in actuality I just need to poop? Anyone else experience this?
