Nuva ring and breastfeeding

I am breastfeeding my 10 week old and want to get back on birth control as I got pregnant after 2 months of trying. I was on nuva ring before I got pregnant. I read on their website to not take it while breastfeeding because it could make your supply go down. I called my doctor back with my concern and she said it was ok since my supply has been established. Has anyone else been on nuva ring while breastfeeding and seen any changes in their supply?
