Congratulations on your 3 year anniversary! I recently started using a menstrual cup and the only thing that I'm sad about is that I didn't start with this sooner. It's amazingly great in every way!
The best thing that happened to women in modern times. I could probably even say that it's the best thing that has happened to mankind.
It doesn't leak at night as pads do, it's cheap and environmentally friendly, but mainly that it doesn't dry out my mucus membranes and doesn't contain bleach and pesticides that I don't want anywhere near my uterus.
