Ftm - 36 weeks, idk if this is normal...

I posted late last night and only got one reply so im asking again to get more advice. I have been having a really bad lower back pain (it’s constantly there) and my vagina hurts extremely bad. I’m at the point where I can’t even walk. I have also been feeling movement really low like in my pelvic area and the movement is scratching or popping like. I’m in so much pain.
