Hi, my last period was 11th Sep. I have PCOD and I had a laproscopic operation last Feb. After 6 months of no period, my first 2 cycle, I did not ovulate. I was on Dupahston. So periods were coming regularly. During last cycle doc kept me on syphene 100 and Dupahston. Today is 35th day, period has not come. What should I do?
