My name is Deepi, and I am 27 year old. I am having irregular periods from past 7 months. In last 5 months I had my periods two times only. my last period was dated 22 Oct 2015. I consulted a doctor on 12 October, and I was diagnosed with having cyst in my left ovary through ultrasound. She gave REGESTRONE (5mg) Tablet for 8 days and then I had my periods. But after that again I didn t had periods in November and December, then again I consult a doctor and she told to have thyroid and CA-125 test and both test was found negative. She told me to tablets MEPRATE for 5 days twice a daily, but still I did not had my periods. Then again consulted her and she told me have MEPRATE again for days but still I don t had my periods. I am sexually active and I also take birth control pill once a week. I also did pregnancy test at home so many times but results was always negative. Please help me and give a solution. Thanks.
