birth control
"I have no pattern but I certainly feel like I have my period 3 out of 4 weeks. And it's been almost 2 years. That sucks, but, it's not enough to make me want to remove it early. I don't have any scarring from insertion and I've had no other side effects. Ended up having to buy a moon cup though as the cost of sanitary towels and the feeling of constant use of them was getting a bit much. I would still recommend it."
