I'm 37, have been using tampons with no problems for about 20 years but for the last 6 months or so I've not been able to use tampons. It's like something is in the way?? I can't get high enough to not be able to feel the tampon if that makes sense. Does anyone know what this could be? My periods are really heavy so I usually need to use tampons and towels together. My dc are 6 and 4 so I haven't given birth recently. I have a scan appointment soon for unbearable pelvis/back/period pain that is quite a recent thing too so maybe they are connected, I don't know. Just feeling very worried at the moment!
