PLEASE HELP

So when I was a sophomore in high school I remember giving this guy a blow job and swallowing. For some reason I have this crazy fear(far above a normal amount) of having an std, hiv and aids due to the media. Could I have it? There were no cuts of any sorts in my mouth. Since then I have done that with 2 other males, one of which I've been with for nearly two years. What do you guys think? If I go to planned parenthood to get tested will they need medical records and will my mom find out? I'm 19 now so I'm still under her insurance and all that. Any input, advice, and experiences would help greatly.
