birth control
"I've been on this BC for about 6 mo. It's done it's job as for not allowing pregnancy, so I give it a 4. But for the first 2 weeks I was on it I was so sick- waking up at night drenched in sweat, lower back pain, cramps, no appetite, my face broke out, you name it... Now I only have cramps off and on, bloated, my period is lighter but I have been depressed for at least 2 moonth my appetite goes from nothing at all to wanting to eat everything. I have NEVER cried this much in my entire life. Also I will get headaches for a week to 2 weeks straight which has never happened to me. 
Everyone's body is different, this pill might do great things for you but it has not worked well with my body."
