Swollen fingers: Can't Get Rings Off

Renita
So over the past week or so I've noticed my fingers have swollen. I am 37 weeks. With them being so swollen, I can't seem to get my rings off. I've managed to get my wedding rights off but I have a ring on my right hand that isn't budging. 
Any advice on how to get it off? I've tried, oil, soap, windex and floss
Maybe I should focus on reducing the swelling first? But how?
