Help??

Hi so I had a sexual encounter with someone a few months ago (oral) and I swallowed there semen , they told me they were clean and didn’t have anything but I have this big fear of catching anything so I am kinda freaking out!!

Do you guys think that I could’ve catches anything from oral?

I plan on getting tested soon!

Also… I did go to the doctors last month for a physical they took blood and my urine. Do they check for STDs while They check for things?

I also went to the hospital for a head injury they took blood would something show up then???
