Hi everyone for the last 2 days I've been getting numbness in my left arm and leg. I'm 9+5. I've also felt my hips starting to loosen like a clock unwinding lol and a couple of clicks in my pelvis. Is this normal? I don't want to be one of those people that freak out at every little thing I feel in my body but I was just wondering. Should I call my midwife?
