birth control
"I started the first patch ,first day of my period as instructed by my obgyn and it was perfect, side effects were almost non existent. My period actually got lighter and less painful. First week was ok, second week I suffered from some joint pain then severe stomach aches and finally vomiting . Spent two days barely able to eat or drink anything till I took off the patch and immediately felt better. If it wasn't for the stomach problems I would definitely recommend it since side effects are the least compared to other methods ."
