Thank you for your query.
You do not mention your age, Your menstrual history, Or if you are taking contraception
. It is difficult to give you an accurate diagnosis without a good Hystory. The most common cause of your problem is a hormonal deficiency
. The best solution to this taking a contraceptive
pill that has good cycle control. I Do suggest that you have a gynecological examination if you have not had one and this must include a PAP test, this is to exclude any infections. I trust this information is helpful.
