Talk to Gynecologist on Continuous Monthly Cycle

My daughter had her first period 1.3 years ago. For first 5months her cycle was regular and monthly. After that she is on her periods almost through out the month. They just go away for 2_3 days and come back again for 10-15 days. Her ultrasound report is totally fine and there is no medical issue other than that. But due to continuous blessing her HB is low (10). I have seen doctors and they are of the view that she should not be taken hormones at this early age. But she is fed up with this now. Her health is being affected.
