birth control
"Although the spotting does suck , its 100% effective. I would recommend it to everyone. I still have normal mood swings, bloating and cramping , but nothing like what I've read in some of the reviews. The only real side effect I've gotten was a really bad headache and the spotting. 
Best Perk, I don't have to worry about getting pregnant for 3 years. Suck it up ladies and use it. I didn't get mine to reduce my periods, I got it cause I don't want kids."
