Braxton Hicks?

This might be a dumb question, but with my first pregnancy I never had any pains at all the pointed towards labor or Braxton Hicks. Nothing “out of the normal”. Bubs got taken out at 36&5 for preeclampsia.

I *think* I’m having Braxton Hicks? I’ve heard that for some people it’s like period pains and then I’ve also heard your stomach tightens up when it’s Braxton Hicks. My stomach has definitely been tightening up on and off since yesterday, so I was wondering if this sounds like Braxton Hicks to y’all? Any help would be appreciated! I just want to know, obviously not worried about anything. Just want to know if this is the correct “feeling”
