Help!! Pelvic pain that brought me to tears

Brigid

I am 35 weeks almost 36 and my pelvis has felt like it is broken in 2 for some time now but just yesterday it literally brought me to tears! I feel as though I can’t sleep because sleeping on my side causes the inside of my pelvis to hurt so bad it burns! Then when I get up just walking about brought me to my knees!

I am going to ask my OB on Wednesday but wondering if anyone else has dealt with this and what I can do?!

Not my first kiddo either but very very pregnant!!!
