What Are The Red Spots On Roof Of Mouth?

Hello,

Yesterday I woke up with a sore throat and noticed a few small red spots on the roof of my mouth. The spots are flat and do not hurt. Today, my throat feels better but I have symptoms of a sinus infection and the spots are still there. I am a 28 yr old female and I have never seen these spots before. I am very concerned and I do not have medical insurance, so I most likely will not be able to visit a doctor.
