"this was my first bc as well, after being on this pill for 3 months my periods were more painful. i also noticed my sex drive went down as well as my energy. it&#039;s pretty normal about a week before my period i would have breast pain. but my breasts would be painful for 3 weeks or more before my period. i finally went the iud route and am loving it. i have noticed how much happier i am! i would highly recommend anyone to not use this medication."
