i used a diva cup w/ IUD b/f I had the whole damn mess taken out! (best.decision.EVER!)
anyway, i did like the diva cup before my uterus went nuts & i was dealing with like 16 oz of blood & chunks per day. The cup was particularly awesome for bike rides & being outdoors where it's a pain to haul tampons or whatever with you. I would totally recommend the diva cup to anyone, especially if you have "normal" periods.
Eventually it got to the point a few months before the hysterectomy that i just went back to pads b/c i got sick of dumping the cup out so often.
