I am suffering from thyroid since last year. I get to know about it in january when I didn't receive my period from three months. I took medicine for two months, then skipped. Levels fluctuated from 20 to 8 to 13 to 11 like this till July. In September I again started medicine and didn't go for examination but, and Lastly I got my menses in August. After that till the date I didn't get my period and I went for test in December end, It came out to be 40. I am very worried as no medicine is affecting me, What should I do? Please help me.
