Have Irregular Period, Trying For A Baby. Taking Norculet. How To Regularize Period?

Hi, my name is sadia jahan ayon from Bangladesh. I am 25 years old, 80 kg, married 2 n half years, no baby. I m going to explain my case from last 1 year to present so that you may understand. In 26 August, 2011 I was on my regular period. As because of my husband came from abroad that time n having physical relation, I got stuck with my period after that regular period for next 3 months. That time my weight was 70 kg & it was started to increase like 75 kg. Then on November, 2011 I meet a doctor who gave me almost 8 tests ( diabetes , blood sugar , blood red cell percentage, blood white cell percentage, urine test, ultrasonograph etc.). All the reports got normal. She suggests me to have a tablet named Norculet-5mg to making regular period. She also said that, when my period will be regular then I should try to have baby. According to her prescription, I was having that tablet from December 2011 to February 2012; period was coming back on track and from March, 2012 to May, 2012 my period was on track. On June, 2012 I had tried to conceive and for this there was no period on July, 2012. But on August 3, 2012 there was period. That period continued above 5 days and that’s why on 16th day of period, I started to have a tablet named Primolut N . After having 1 tablet, that day my period stopped but I was continuing to have that tablet to complete the course. On 20th day again my period started again normally. After that time, up to November, 2012 my period was regular. Then again I tried to conceive on November, 2012 and the same problem started again, i.e. on December, 2012 there was no period. Then on January 13, 2013 my period started again and still now it’s continuing. Now, what should to have a baby and how to regularize my period? Can you please give me any hints or any solution or any reference of a good doctor? You can email me: YYYY@YYYY
