Prolapse?

I’m nearly 3 weeks postpartum and it’s been hurting all day to sit down, I’ve been feeling weird pressure. It hurt when I wiped going to the bathroom (I didn’t tear) and felt sensitivity that I hadn’t felt before. I stood up and washed my hands and then grazed my finger across the opening of my vagina, not inside, and a portion of my cervix is just outside the vaginal opening. My immediate thought is uterine prolapse, but is it normal for the cervix to be this low so early postpartum? Or is it for sure a prolapse?
