"after an episode of erythema nodesum from my last birth control pills, my doctor suggested i try a 3 month course of micronor to see how my body would react to the progesterone.  well, i&#039;ve gained 5lbs and had my period or spotting 27 out of the 42 days i&#039;ve been taking it. 

my doctor wants me to continue on it to prepare for an iud, but honestly i don&#039;t want it if the breakthrough is going to be this problematic."
