I found out a couple of month ago that i have pcos. I also since i was 11 years old have had acne problems and irregular periods. But about my acne it wasn't that bad when i was a teen but since i was 22 - 23 years old it had gotten worce.
I am now 25.
I found a site about pcos and acne. My hormones are going crazy. Someone recomended to take "Vitex" you can get it at GNC for about $20 maybe less. it gives you 100 pills. it will help with your pcos. My periods are starting to regulate again. It's been a very long time since i had my period 3 months in a row.
I have been taking Vitex for almost 4 months now. My acne has subsided it's not as bad.

i hope that it will cure it.
I am in the same boat with you about going through puberty again. Along with that. I am starting to get dark hairs on my chin and side of face.

i hope it don't get worce.
I would try out the Vitex for a couple of month. I know it will work for you.

good luck
