Pelvic pain?

Does anyone else have extreme pressure/pain in their vagina? Like your baby is pushing down really hard? And it hurts worse to walk or move. I am 30 weeks tomorrow and its been like this for a couple weeks. I have an 11 month old and never had this problem with him! It freaking hurts so bad and he weighs like 28lb and has been soooo clingy and needy lately and i can barely pick him up bc of it!
