I am 20 yrs. My problem is that my periods stays around for about a mont, and more than that. I would like to know what sort of problem I have and what should I do to get rid of it?
You may want to get a thorough GYN examination. If that is okay then perhaps trying birth control pills might help you regulate it. Good luck.
Your problems seems to be low level of progesterone (most probably). PCOD won't present with such features ( Very rare). Better get your hormonal profile completely. You might need hormonal pills depending on that. Supplementary USG pelvis will be more helpful.
Check LH, FSH, TSH, progesterone levels.
I can suggest more if I know your weight.
