Hi. I performed oral sex on a male (a stranger) on Thursday (today is Tuesday). Shortly after the or sex I developed a sore throat with swollen tonsils and my tonsils also got white spots on them. I thought it must be from the oral sex. I went to the doctor this morning with intents to tell the doctor about the oral sex but I am a little shy and got nervous because I didn't just see the doctor, but I also saw a nursing student working with the doctor and a lady nurse andand being seen by a combination freaked me out, even though I know I had nothing to worry about. I didn't tell them about the blowjob, which I now regret. They tested me for strep and mono. Both negative. The doctor told me it was viral pharyngitis. I received a shot in my hip which I've forgotten what the doctor said it was called but I want to say it started with a c or d. I also was prescribed Z-pak antibiotics... Or generic zithromax. 250mg tablets . Which I was to take two of today and one each day for the next four days. Is it most likely I did contract an STD? And can I still get tested for an STD to be sure? Should I call the doctor and tell him about the blowjob after the fact? And make sure I'm on the right treatment if so? Thanks
