What could it be?

Im 32 weeks and around 2 am I started having bad pain in my vagina not the outside but inside and kinda way up like around where I've been checked and the can feel my cervix and had a ton of pressure in my pelvis and felt like I needed to push several times. I didnt but it was really hard and now I'm up bc the pressure and pain is keeping me up. What is this or could it be going on?
