Hi.. I have irregular periods, it happens once in every 5 months.... Last time I had chums in the first week of November 2015...I consulted a doctor and she prescribed Cyclenorm P and E and also APCOD...the doctor asked me to go through thyroid tests as well, now I suspect if it is due to thyroid and I'm worried about my health...I'm still 22 years...can someone please suggest me what can be done at this stage??
