birth control
"I started this pill and all seemed fine.  I had some symptoms while my body was "adjusting" to the hormones: breakthrough bleeding, a little weight gain, feeling blue.  But I guess my body never fully adjusted because 6 months later, this pill is giving me headaches, I have breakthrough bleeding in the middle of the month every month, I feel slightly nauseous all throughout the day, and I still cramp and get acne.  I didn't get pregnant though, and my periods were super light and short, but this pill just doesn't work with my body, I think."
