Do I have Herpes?

I had unprotected sex multiple time over the last month. A few days after my last encounter i started to feel a little sick then started to feel like complete shit. I did not get tested for COVID but I had the exact symptoms and my parents tested positive right when i was getting over it so i just chalked it up to that. Until this singular white-yellowish bump showed up right below my penis head. I have experienced zero pain from it nor has it burst but it has been here for about 2 and a half weeks now and I’m kinda starting to freak out. Please if any of you know what this is please let me know!
