Hello, and I hope I can help you today. There are several medications that can be used to help make you get your period, but it depends on the cause of the problem. Missing your period can be caused by pregnancy (which i assume has been ruled out), stress, being too thin or too heavy, hormonal imbalances, and some medical conditions. In young women, the easiest way to manage irregular menstrual cycles is with birth control pills. No matter what the cause, birth control pills will make you get regular, light, predictable menstrual cycles. I usually use birth control pills as a first-line treatment in patients unless they desire pregnancy. There are many different kinds of birth control pills on the market, and a GYN doctor (for female problems) usually can recommend a type that will work best for your particular set of conditions. I hope I was able to adequately answer your question today and that my advice was helpful. Best wishes, Dr. Brown
