I think I might have tourrets?

Ok so for a little over 2 months now iv'e been hiccuping everyday. But the thing is it will only be 1 or 2 hiccups randomly, out of nowhere. it's not like a usual hiccup thing where you'd hiccup like a whole bunch of times. The number of hiccups per day varies. I've tried many methods to get rid of them and they didn't work. i've even gone to my doctor and he doesn't even now what it could be. And these hiccups aren't the quiet kind, and its really embaressing ( especially when i do it in the middle of class) when i hiccup because sometimes it sounds weird and people look like wtf was that. It doesnt't hurt or anything but im just really anxious to find out what it is.
