Anna,
You very well may have pink eye BUT, it could simply be that your sinuses are draining into the eye. I often have the exact same symptoms as pink eye, but it's actually the drainage. If the antibiotics don't work in a couple days, then it's likely not pink eye. (There is nothing to "fix" the other problem, but it's usually short lived ~ a couple days~ and no real health concerns, and NOT contagious.)
Good Luck,
Heather
