birth control
"Love this. I switched from a combined pill because of migraines, and will never go back. I haven't had a single period on it, which my doctor has informed me is completely normal on this pill. I have not experience mood swings, weight gain, or changes in my skin. The only (slight) drawback of not having a period each month is not knowing for sure that you are not pregnant. For someone like me who is predisposed to anxiety, this can be stressful."
