Hi and thank you so much for this query. I am so sorry to hear about these irregular periods since when you were 19years old that are being controlled with hormonal pills. Irregular periods that are controlled with pills usually get regularised after using hormonal pills. This occurs because of the immaturity of the hormonal control mechanism. What has to be done is that the drugs have to be stopped after a while on treatment and the cycle observed for a few months to tell whether it has become regular or not. It does in a majority of the cases. We cannot continue treatment indefinitely unless any attempts to get you off this drug has failed. And if this is the case, then other causes should be actively investigated and addressed accordingly. My advice is to talk with your doctor and see what your periods will look like without this drug. This will help you know what to expect and open the floor for further discussion on why the cycle cannot take control of itself without hormonal pills. Hope you find this helpful. Please, feel free to ask us more question if they do come up. Thanks. Dr. Ditah
