Hello, and i hope I can help you today. When I usually prescribe medication like Deviry to bring on a menstrual cycle, the dose i usually prescribe is 10 milligrams for 7 days. The dose you took may have been too high for you, or too short a time period.... or... Did you do a pregnancy recently? That could be another reason why the Deviry didn t work. Don t worry, the hormone in Deviry in another form is used to prevent miscarriage and therefore is safe if you did get pregnant. So I would do a preganacy test if you haven t already, and if you are not pregnant, I would recommend you discuss with your doctor an alternate dose of the Deviry for you, or consider a fertility medication, which also can make you ovulate and get a period. I would especially recommend this if you have been trying to get pregnant for more than a year. Also, if you are overweight, low-carbohydrate diet and moderate exercise 30 minutes 3 days weekly can help improve ovulation. I hope I was able to adequately answer your question, and that my advice was helpful. Best wishes, Dr. Brown
