Something is wrong with my vagina

Junie

So I just noticed in the last month or so, something is different with my vagina. My bf is also larger but we've been together two years and I'm just now having issues. So it seems like when my bf enters me it hurts my cervix. The first time it happened I actually ended up bleeding after and it was actually a decent amount and I felt sore.. i haven't bled since but i still have pain when we have sex, but it's not my ovaries its definitely around my cervix. Also right now i have my period and it just feels super uncomfortable to wear tampons, which I've used the same brand for years so that's also weird. I do have an appointment on the 23rd but I'm just getting nervous on what this could be.. I have no other symptoms, no smell or weird discharge. When I put a finger inside it feels like I'm swollen in there.. Anybody have an idea?
