I don't know if worried is the word I would use, but I would follow up with your doc and just make sure nothing else is going on.
If they think you might have an std, make them test for it, and ask what the meds are that you are getting, and why, and what std they think you might have.

They gave me alot of antibotitics for all the stds, but my girlfriend doesn't have anything wrong or anything so should I be worried.
This isn't likely to be due to an std, but you should follow up with your doc. It might be normal, but you need to know that.
And in the future, when you get treatment for something, you need to find out what you are being treated for.
