Does Spironolactone cause weight gain?

my doctor put me on 25 mg of Spironolactone twice daily to help hormonal acne. I was researching reviews online and many women have said it caused weight gain and cellulite, and that you can have a bad breakout when you first start on it. my Doctor said most his patients started seeing results within three weeks and did not experience I intial breakouts. Wanted to know why and if Spironolactone can cause these reactions. Is cellulite because it effect estrogen levels? I'm nervous to start it
