Postpartum pain

I’m now 13 months pp and I have noticed ever since giving birth that sex hurts. Without going into too much detail, I can feel my husband hitting my cervix, it use to be pleasurable but now it flat out hurts like I’m bruised. Even if we wait a week or so it still hurts. I’m kind of worried, has anyone else experienced this? Is it just something that happens after you have a baby? Making an OB appointment to get looked at 🥴
