Pelvic pressure...

I'm 36 weeks and baby Lukas has had his head buried in my crotch for a few weeks now. Today though it hurts! Bad! I can feel every head but he does to my poor bladder n spine. Going to the Dr today to get checked. His due date isn't till may 29th-june 6th so I'm hoping it's just him being a little turd. Anyone else hurting so early?
