I wouldn’t be too concerned about the pap smear being one year late. When I got mine done, the doctor explained that it’s just a precaution when you’re younger, and you really only need to go more often when you’re older like 50+. As for the pain, that sounds horrible and a bit concerning, but don’t worry yourself too much with crazy ideas. Sometimes people have more shallow vaginas, or a thicker hymen, or whatever. There’s a LOT of things that could cause that and a lot of them aren’t scary.
