Crying In pain - please help

Currently 35 weeks and I'm having insane pelvic pressure and pain. I can literally feel the baby is sitting on my pelvic bone.

Is it normal?

Do I rush to the hospital? ( Happening from past 2-3 days) . Apart from that the baby movement is pretty normal. Also, I'm putting pressure while taking a poo. Could it be because of that? I kept getting constipated/have diarrhea. Nothing is certain, somedays I have diarrhea and somedays I'm constipated.

Any other mum feel this way?
