I was bitten by a dog 2-3 months ago?

I never found out if the dog had rabies or not. I have been feeling ok, but after further information, I found out that there is an incubation period, and since my bite is minimal, and right bellow my ock, I'm worrying that it might take a long time to be in incubation. Do I still need to get checked? and is it too late to get treated??I'm really worried
