This video was great and answered a lot if unanswered questions! I have PCOS and I can honestly say birth control is a great way to regulate your period and control hair growth. Before I was on it, I didn't have a period for 9 months (terrifying to a young girl then and my chest, back, and facial hair was out of control. I've been on it now for about 4 years, and my hair growth is normal and I'm having a period every month. If you have PCOS, consider getting on birth control.
