You should ask your doctor. But my guess is that unless there was damage that could cause a scar or scarring, you probably healed from this. I assume you have had standard ob/gyn pelvic exams since then? If your vagina or cervix were scarred, the doctor would be able to see. And I assume that if the nail-polish remover made its way into the uterus, you would have known from how it felt. Also, the uterus sheds its lining once a month, and that gives it a chance to clean out any scabs or debris. Have your periods been normal? You're probably fine.
