Suggest Treatment For Irregular Periods

Hello Doctor,My name is Nithya and I reside in Kengeri,Bangalore. I have been working since 2002 and I work in night shifts. Since I started to work in night shifts, my periods has not been regular. I get my periods once in 3-4 months. Throughout all these years, I have consulted few doctors regarding this problem and for about a year, I took homeopathy medicines and right now I am taking Kottakal Ayurvedic medicines. The result is not satisfactory. Its been 4 months now and I din't get my periods yet. When I took a scan for about 6 months ago, doctors told me I have Polycystic ovaries. I am not sure if I have thyroid. I got married last year and I still work in night shifts. Its high time I need to get this periods problem resolved and become pregnant. There is a lot of pressure from my in-laws and they pressurize me to deliver a baby soon.I just want to go through proper medication to get all these problems resolved. Please help!!!Please call me at 98864 02130ThanksNithya
