i’m 21 weeks and when I move around a lot I start hurting down low under my belly on the right side. it’s like when I walk it hurts but if I sit down and not do to much it leaves. I started working so im on my feet a lot is this because it’s to much on my body? I have a 3 year old and a 2 year old and I pick them up still to put them in the car.. idk if that’s is playing a role as well..
