"was on it for 3 years. mostly used to help treat pms, cramps and headache. while those never really went away just delayed 3 months were less severe, until recently. lately been having horrible cramps about a week before, and some mild spotting. did not have my hormone headache and cramps were tolerable with one month bc. recently talked to obgyn , she thinks this is my bodies way of telling me should have my period once a month, so back to the one month packs."
