What's up with my eyes? ?

(21 year old female in good health) A few days ago my vision started getting blurry, I Ignored it and just went on with my day thinking it would go away. Then yesterday it got a little worse followed by a intense throbbing headache that lasted 6 hours or so till I went to bed. Today my headache is very faint, almost gone but my vision is much worse and is more "fuzzy" than "blurry". (As a baseline usually I can see Everything VERY well don't wear glasses ect.) I guess my question is, is the onset of fuzzy vision usually this quick and I'll just need some glasses? Or should I go to my general practitioner? Has anyone had this experience before? (I have an appointment with an optometrist in one week) thanks! Sorry it's so long :)
