Any tips ??

Hello. I'm currently 29 weeks pregnant. For the last month I've been experiencing some very uncomfortable pain. I hurt sooo so bad below my belly and pelvis area and my back, omg. It's like I get so stiff and there is so much pain when I try to move while laying down, when I try to get up, and sometimes when I walk. It usually comes and goes by its been going on for a few days now. I didn't experience this with my first pregnancy. Any tips on how to ease the pain??
