Rings?

Okay this is my first pregnancy so I'm not sure about a lot of things. I'm only 11 weeks. I noticed my ring finger was aching and it looked swollen and for the life of me I couldn't get my ring off! Which is weird because it's the perfect size. Lathered it with soap and had to slide it off but it was soooo painful passing over the swollen bit! Do your fingers get fatter in pregnancy?
