Hi.. I generally have very irregular periods. In some months it occurs more or less in proper time, but mostly it's irregular. I want to have an USG done to confirm if there is any other internal problem. I went to one gynaecologist once last year for this problem. She suggested me a pill which she asked me to takefor a week. After completing that dose, periods started that month. For some few months after that, it was more or less regular. But again now I am having the same problem. Please suggest, what should I do?
