I am 21 years old. I have been suffering from irregular periods since past 4-5 years. Initially it used to start late. Then it crossed 2-3 months and it didn't flow. That's when I seek help from a doctor. She gave me that course of 21 days which was to be taken for 3 months straight. So when I used to take those medicines I used to get the period but as the course was over I didn't get my period next month. Thus again and again I took medicines as per doctor's prescription for all these years but nothing gave a lifetime solution. Last year I also got an ultrasound test which came normal and just 3 months before I got a hormonal test done which again was normal. Doctors are unable to tell me a solid solution for my problem. Would I have to keep taking the medicines life long to get my periods?
