birth control
"I've had mine in for over six months now, and I love it. My periods were light before insertion and I've never had cramps. For the first three months after insertion, my periods were very heavy, but the blood flow has decreased every time. Still no cramps. Very painful first day of insertion, but 100% worth it. I also love how there are no hormones and its long lasting. Would highly recommend. But, if you don't mind hormones and have a heavy flow, go with the Mirena"
