do you feel the menstrual cup when exercising?

I'm training for the military, and I want to try to quit using tampons unless I absolutely have to. I know in boot camp I'll probably have to use tampons or pads, but until then, I hate how they make me feel. I'll looking into the menstrual cup, but for the next few years (at least) I'll be working out almost every day. I feel like sit ups would hurt.
