Nuvaring and Nausea

Due to me having high blood pressure and multiple problems with my mental illness as of late, my family doctor took me off of the pill and switched me over to Nuvaring. 
I've had it in for three days now and each night/early morning, I've been really sick to my stomach to the point where I feel like I'm going to vomit. This is causing a problem for me because the sight/smell of food or anything in general just makes me queasy and I have to pull six hours shifts at work sometimes without getting a break to eat (I get dizzy very easily). 
My question is for those of you who have used/are using Nuvaring. If you suffered from nausea, how long did it last before it went away? I know it's different for every person, but I just want an estimate because if not, I'm going to need to make another trip to the doctor's office.
