Have u gained weight recently. As per what u r describing u seem to have PCOD. It's not a disease but a change which has happened. U may need treatment after marriage for conception. At present don't do anything about periods, u can bleach the facial hair.

Hello there we understand how you feel.and your condition totally but you need to know that this is a type of situation where it needs an expert intervention. This need to be evaluated by a gynecologist and to be treated by her eventually so. It would be wise of you if you can consult a gynecologist for your help and get relieved of this. Thank you.
