Hi there, Welcome to HCM, The symptoms irregular periods sometime short sometimes long is more due to an-ovulation, due to hormonal imbalances. The ovofar is to correct that. You probably have PCOS, which is causing the irregular cycles and which is why the doctor has prescribed you the ovafor. You need to first get completely evaluated for PCOS before proceeding with the treatment. I would advise you to get the blood tests such as FSH,LH, TSH and prolactin done. These will help determine if the cause of irregular cycle and infertility is them. You also need to do ultrasound pelvis to check for problem is in ovary and womb. Your partners semen analysis is also necessary to get a complete picture. Kindly do the above tests and discuss with your gyanecologist. If PCOS is diagnosed by blood tests and ultrasound, medications such as metformin need to be started. Hope this helps. Regards.
