What are Braxton Hicks contractions?

Alysha

Sometimes. I get an all over stomach tightening feeling it just feels like well. That my stomach is tightening and it’ll stay that way for a minute then stop and it won’t happen again for hours or days even. It doesn’t hurt at all except maybe a slight twinge in my lower back for a second but nothing more than that. I’m 28 weeks and 2 days. I know it’s normal. But is it Braxton Hicks or just something else? 😅
