Idk how to ask this...pain in crotch area?

The last few days, my vagina has been really sore in the morning...kind of feels bruised or something. It goes away as the day goes on but I can barely get out of bed because of it. I have to hold my crotch and roll out. I feel like it's probably a normal 3rd trimester symptom (maybe my pelvis changing so baby can come?) but I'm not sure. Does anyone else have aches and pains like this? Any remedies?
