When I stand long

Vanessa • I am 37 years of age, married with 2 big girls. My oldest is 15 and my youngest is 13 and my baby boy is 5 months old.

So im 25 wks and everytime I stand too long or clean long I get sharp pains under my belly. Even bad pains in my lower back. But im really worried about the ones in lower abdomen area. Anyone know about this pain?
