birth control
"I had the mirena put in 3 years ago. The insertion was extremely painful (I haven't had kids) and I had bad cramps for 2-3 days after. After getting over that first hump, I didn't get my period again for 3 years which was awesome! However, it did cause me to develop cystic acne which I didn't have before so consider this possibility before having it put in. If you aren't acne-prone it's an awesome form of bc!"
