Ladies I honestly need some help . I am 38 weeks and for the best 2weeks i been having EXTREME pain in my vagina bones . Idk if its pelvic pain or what. This week it's been so bad . I take a min to turn from side to side when laying on bed sooo much pain. I also feel it when I lift one leg to wear a pants. I could never move one leg while other not .
