birth control
"I'm 26, child-less, and cursed with painful, heavy periods. After trying pill after pill, I spent 4 years without birth control. Decided to try Skyla after an OB GYN and friend recommended it.  Not going to lie--- worst pain I've ever felt having this thing put in! The 6 weeks following I bled almost everyday and had little random lightning-storms of bad cramps. After 3-4 months, my period are lighter and my PMS symptoms have improved. I still have bad cramps for a few days each month, but I'm finally glad I got this IUD. Husband doesn't feel it, and it's nice not having to use condoms. On top of that, I think my appetite has decreased - not sure if it's related. 

In a nutshell, I recommend it. Just expect an adjustment period of time"
