Hi.. I am 23, my weight is 97 kg and height is 5'8". I am having periods irregular prblm from many years since I started having periods. I started treatment at the age of 15. That doctor gave me Ovral - L. and I had that tablet for around 8-9 months. i usually get periods at that time after taking medicine. after that I stopped that medicine and sometimes I had periods and sometimes I missed it. In 2011, I saw a doctor where I had all my tests, she said tests are normal, just take primolut-N, to get periods, I used to take that medicine alternate months and got the periods only when I took medicine after 5-6 days after completeing the 5 day course of that tablet. and now, from last 6 months I didn't had my periods. and took the medicine on 15-11-2013. and it got over on 20-11-2013. Its being 6 days, I didn't get my periods after having the medicine. what should I do now. I am alsohaving breathing problem from last 1 month. got examined. lungs test, chest xray, thyroid, these are all normal. some doctor said its may be cause I didn't get periods from 6 months, I am facing this problem, plz suggest, what should I do now. I am feeling irritation and watery in the lower part from last 2 days. but not getting periods.
