Delay in periods. What should i do?

Hi I have pcod and trying for a baby. I havedone all my tests, sonographies and follicle studies this year in April may. The doctor has said everything is fine . Only that I have pcod and due to that high estrogen levels. My follicle size was also less for which I was prescribed medicines. After having the medicines my follicle size grew but we couldn't try that time due to some family emergency. This happened in may. After this I got my periods in June. Then since we were shifting to Pune we thought of showing a doctor in Pune after August. After June I got periods in August and now it's been 2 months I am not getting my periods. We have not tried during this time so I know I am not pregnant. I m worried thinking it's pre menopause and I m very disturbed since I was wanting a baby now. What should I do?
