There's red spots on soft palate, yellowing where tonsils were and possibly white spots on back of throat?

Mouth spots. Do you have any pain and/or fever? Do you feel very tired and worn down? If so, you might be experiencing strep throat. Have you recently engaged in oral sex? If so then you could also have an STD. Go to your doctor ASAP and get it checked out. Many common conditions once diagnosed can be treated with antibiotics.
Sore throat or not? If sore throat, go see your Family Doc to discuss testing for Strep. If not, this may be normal for you. If you engage in unprotected oral sex, then you should get tested for sexually transmitted diseases/infections too.
