"i have been taking this medicine for almost 2 years now due to horrible cramping. no medicine worked for my cramping and i was taking to much medicine. when i first began the pill my body was way out of wack, pain, sleeping alot, not to much eating but after about 4 months my body got used to it. so i think the pill does help to prevent pregnancy very well and it does indeed help with my cramping even though i may have to take a pain pill a few times. levora is pretty good. you have to be careful about going for more then two days without taking it because you will bleed like a period and it will last for 2 weeks. i am adjusted to it now."
