I Am Taking Amox Tr-k Clv For A Wisdom Tooth

I am taking Amox Tr-k Clv for a wisdom tooth extraction, one week ago. I have just developed a rash over 50% of my body. I think it is an allergic reaction to the medicine. Should I take the last 2 pills? I'd like to stop them. When the dentist pulled the tooth, he said it was clean and just wanted to prevent the risk of infection...but it feels fine. What do you think?
