Question⤵:

I'm 35w... and for the last few days my last part has felt bruised. like a straight tender spot right where you feel the bottom of the pelvic bone. I haven't had sex or fallen anything different. She's fine, moving and everything. Jw is it normal, what could it be, is there anything I can do to ease the soreness? I go to my OB tmrw btw.... 😩😧
