Pelvic pressure/pain

I’m already going to the hospital to get checked out, but I’m curious if anyone else is experiencing this. I am 20 weeks today and last night while I was standing in the laundry room folding laundry I got some pain and pressure in my pelvis. Like in my vagina right in the center. It’s a constant pressure when I am standing up, but when I am sitting or laying down I am fine. I am wondering if that has been normal for anyone else? Have you seen a doctor about it?

****UPDATE****

Went to the hospital and doctor said everything looks normal that baby is just in an uncomfortable position.
