I have a paragard iud and I normally wear pads. I do have a menstrual cup that I use when I go rock climbing or hiking, which is about 4x a week. I've noticed that when I wear my cup, I seem to get mild cramps after awhile. I normally cramp on day one, sometimes day two. after that they taper off and go away. the cramps from my cup usually start an hour or so after I put it in. Not sure if anyone else has this problem, but i can't use pads when I work out a d tampons are way too uncomfortable for me. Any ideas?
