I was on yaz for only 2 months and quit taking them when I got down to my inactive pills. I had a period/bleeding for exactly a week, (normal since i quit taking them), ever since then my breasts have been tender . It has been 2 weeks now since I quit taking the pill and they're still tender. Is this normal? This isn't the first time I've ever come off of birth control, and I've never had any change in my system, other than simply waiting for my period to start up again. Also, I'm not one to have breast tenderness as a pms symptom.
