I been taking Levora since May. I been skipping my period starting June by not taking the inactive pills. I never seen any stopping nor bleeding up until now. In November I started seeing a brown/red spot then it lead to what seems like a full blown period. I am not pregnant as I am no longer sexually active. I also received a doctor blood work which showed negative the past 3 months of not being pregnant. I have no infections either. What can be the cause of this drastic period. I haven't had a period since June.
