What is this!!!

It feels like baby is kicking my bladder really hard, I get this cramp and I say owwww! I can't move, then there's pressure in my rectal area feels like there's poop there but there isn't. I'm 38+2 what are these pains? It feels like I reallllyyyy have to pee! But when I go manage to get up there's a ton of pressure in my vagina and I pee very little.
