I'm on Risperidone, but I don't think it's changed my period. Then again, I've just assumed the changes were caused by getting older. My period does the same thing it did for the first few years I had it, where I have my period for a couple of days, then it almost stops for about a day, and then starts again and finishes a day or two later. It stopped doing that for most of my adult life, but like I said, it does it again now. That's been going on for a couple of years. I'm not sure how long ago I started Risperidone. I do know the Risperidone causes a small amount of milk to express from my nipples.

However, you said you thought you were in menopause early. That's still a possibility. A lot of women's periods stop, and they think it's over, but months later, it happens again. It doesn't necessarily stop for good when you haven't had it in a while. Comedian Rosie O'Donnell said her period stopped, she thought for good, but it came back eight months later. My mom told me she was done menopause at 44, and I'm 45, and still having my period every month, and my last blood tests didn't show me to be peri-menopausal.
