Oral herpes?!

Mariah

Okay so I am on period and break out relatively bad. On my cheeks and on my chin usually. But yesterday I had smoked with my friend and some of his friends. I now have a pimple on my lip that I've popped 3 times in just today. It popped up the morning AFTER I smoked with my friend and his friends... My dad told me "Be careful who u burn with" and said it might be herpes but I genuinely feel like it's a pimple😭 can someone help!
