Menstrual cycle disappeared

I am assuming that you are not/ could not be pregnant? Sounds like you could have a hormonal imbalance. The breast discharge especially makes me think that your hormones are out of whack. I had a similar discharge for years before seeking treatment. Turns out that my body was producing too much prolactin- the hormone that stimulates breast milk production. Your estrogen and progesterine levels could be imbalanced as well, causing your periods to cease. There are any number of other things that can cause a woman's periods to cease. I think you and your doctor need to figure this one out.
