 [ Symptoms ] i have had swollen tender itchy breasts for approximately a month and a half what could be the cause  i am 26 years old and due to my birth control pills i have not had a period in 3 years for the past 2 months i have had a period for the first time during that time frame but for the about the past month and a half my breasts have been extremely tender swollen grown nearly a full cup size and itchy only seem to be itchy when i take my bra off at night i have never missed a pill and am 99 sure i am not pregnant [ Disease ] hi just to be on the safe side either go get tested or do one yourself just in case you do not want a child but be quick as your still in the time frame to abort but please remember some pills are not 100 proof this may account for the hiccup like having a period and there could have been a problem with your pills do hope this helps good luck
