I masturbated before my period start,like 7day before that. 2days after i got brown blood for 4days(maybe more)then i got clean.and i didnt get period one week after and i tried homeremedies till i arrived 50days and i did the serum but still idont?

The brown discharge was likely older blood. If you are saying that your period is now 50 days late, is there any possibility of pregnancy? If so, you should do a home pregnancy test. If that is negative, you should see your doctor, preferably your gynecologist, to be certain there is not any other problem. Anovulation can result in a skipped period but 2 months in a row is unusual. Good luck!
