Is it safe to use Diane 35 for Polycystic Ovary Syndrome, I'm 16 years and virgin, I want to get back my period after I lost it cause I lost weigh.?

There are risks. Diane 35 is a birth control pill and will allow you to have a period regularly but stops ovulation. Other BCP do the same, but Diane 35 has a different progesterone that helps alleviate testosterone type symptoms. It has 4 times higher risk of blood clots than other BCP's and is not approved in France or USA. Get a test first for tendency to produce blood clots.
