"ever since i&#039;ve been getting my period i&#039;ve had dier cramps to the point where id have to miss school for 2 days each month and take sleepy medicine to knock me out. minastrin absolutely releaved my cramps. i will occasionally feel a discomfort but not bad enough where i have to take pain killers. at first when i got it i barely got my period but now i&#039;ve had it for close to 3 weeks. i&#039;m not sure if this has to do with the birth control but probably. if i wasn&#039;t continuously on my period than i would rate it at an 8 because sometimes it gives me mood swings as well."
