I Sweat Excessively Especially On My Face And Sometimes This

I sweat excessively especially on my face and sometimes this is related to anxiety but it can also be random. This only started a couple years ago and my doctor can't find the cause. I have been taking the nuvaring for about 2 and a half years and I'm starting to wonder if this is the cause. Can the nuvaring be the cause of my hot flashes and sweating?
