Can strep throat turn into something more? - strep throat more condition_symptoms.

I was diagnosed with throat infection on Sunday. after receiving the shot and antibiotics per day together with vitamin C, I'm sick today. I do not think strep can do for you ... I feel better after they get sick, but in fear that my symptoms of ill-will return.
I am getting married on Saturday, then I have to 100 percent! Suggestions?
