I am 27 years old and married. I am suffering from pcod since 5 years. My uterus is small (4.7*2.9*2.7)i have been using various types of medications to get periods regularly such as, novelon (1 year), crimson 35 (2 years) and now deviry 10 mg. I get periods only when I use tablets without tablets I didn't get period. I am trying to conceive. So my gynic suggested me to take stimulet 2.5 mg for ovulation and have follicle study. Then I started using stimulet and had follicular study. I got periods for 3 months by using stimulet but 4th month I didn't get period, pregnancy test negative. Then I used deviry 10 mg to get period. I got period. Then again I used stimulet and never got a period. What does it mean? Is the tablet is not working? Or should I continue taking stimulet? If the tablet is not working then why I got periods for 3 months by using stimulet? Please give me a reasonable answer. I am afraid that I will never get pregnant.
