I'm a new cup user, 2nd cycle. I have 5 kids all delivered vaginally and a low cervix. Last cycle went as well as expected- some leakage, some discomfort, mostly going ok. Except this super weird thing where I would occasionally go to remove it and find it way up in my vagina, UPSIDE DOWN. has anyone else ever experienced this?! I'm pretty active but this happens randomly, can't tie it to my yoga of anything.
