dog bite while pregnant

This may seem petty but I HATE dogs. I'm just not an animal person. But my mother in laws dog but my finger. She claims the dog has a had all her shots and I have nothing to worry about. But it broke skin and bled, and this happened about 2 hours ago and my finger is still red and swollen. Should I have it looked at, as just a pre caution??? I know the little mark is small but I feel like it shouldn't still be sore and be red and swollen. 39.4 pregnant btw
