I’m 39/40 weeks pregnant today, Every time I went for a ultrasound they kept measuring me bigger, and last time on 11/10- I was measuring a week a head and baby already at 6lbs 10 oz. with a due date of today....I’ve been having the past couple days excruciating hip and pelvis pain? Like the front of my vagina area is killing me. I’ve had a hard time sleeping at night and barely being able to get up and walk around, the busier I am and the more i move the less it hurts. Any ideas on some relief?? Other than pushing this baby out hahah
