Braxton Hicks

When your stomach tightens with some cramping and is uncomfortable, is that Braxton Hicks?

FTM, and my stomach has been tighten so much it’s basically like that all the time for the last 3 days. Last night some mid to lower back pain started to where it hurts to walk.

I’m wondering if I should go get check out or if this is just pregnancy 🤷🏼‍♀️ I’m 36w1d
