Hi, I had gone through your question and understand your concerns.If I were your treating doctor I would first test blood for thyroid
level,sugar and androgen level.PCOS
may be a cause,so you should done ultrasonography
of lower abdomen and pelvis to exclude that.In case you have any questions in future you can contact me directly on http://www.healthcaremagic.com/doctors/dr-avijit-basak/68560. Thank you.
