Is it normal?

Isabel

So I’m 5 months(20+3) pregnant with my baby girl (third baby

Is it normal to constantly feel my stomach tight sometimes and small cramping? Sometimes I feel like I need to pass gas but that’s not the case. It could last a while until I get up to walk and I’m okay. Is that normal? I feel like it could maybe be Braxton Hicks? But I’m not so sure

She has also been super low all pregnancy, I feel her kicks more in my lower belly

Any advice??
