Irregular periods. In the month of jan.

Hi, I am married for about 9 months now. Until March, my period cycles were normal, in April it got pushed by a week and for the whole month of May I have not got my periods. As of date, my periods have been pushed by 48 days. I tested for pregnancy (kit at home and blood test per advice from doctor in a lab) and both tested negative. The doctor adviced that I take certain other tests to confirm diabetes or thyroid issues - Plasma Glucose(Fasting and 2 hours), Free Thyroxine, TSH, Prolactin, CBC and ESR). All the values look normal but for Lymphocytes count = 41.2%, ESR=38mm and Prolactin which is 25.91 ng/ml. When I browsed thru the internet, I was able to gather several different ways of interpreting these values. I am unable to understand what I might be suffering from. FYI - I have been diagonised with Citric and Dust allergy in the past and have been using nasal and oral sprays for over 11 years now. I moved from Bangalore to Chennai after my wedding in the month of Jan.
