i am 25 years old and sexually active with my bf of 3 years. I used to be able to wear tampons and over the past year or more I haven't been able to wear them. It is painful to insert them adn it always feels that something is blocking it from going all the way in. I use the smallest tampons possible and they still don't go in. I had a PAP smear last August and everything was fine. I am currently on the NuvaRing and I have been having trouble inserting it and having it stay in. I have been on it for about 5 years now and I am recently having trouble with it. I feel like I can't push it all the way in. It is supposed to stay inside with your vagina muscles, but I find myself always having to push it back in. I have a history of ovarian cysts, that is why i was put on NuvaRing. I have my yearly check up next month, i was just wondering if i should go in now to get checked out, just worried and uncomfortable. I dread having periods adn now I want to switch my birth control. Any advice would be helpful---thanks!
