"before minastrin my periods were extremely irregular, fairly heavy, and accompanied by cramps strong enough to cause vomiting, acne, breast tenderness, and headaches. minastrin was a miracle. my periods now only last 2 to 4 days, are extremely light, and they happen at the same time every month and never on weekends. i never gained weight either. the only negatives that i&#039;ve noticed are the first week of pills i was nauseated every morning but that passed, it causes some mood swings that my parents noticed as well, and my cramps haven&#039;t fully gone away but they are much more manageable due to regular period and only last 2 days instead 4. with these negatives though i strongly recommend it."
