Could I have an STD or am I paranoid?!
Question: Could I have an STD or am I paranoid?
Answers:
I would say that you are being cautious, not paranoid. It is the first time for you to have sex, and you aren't sure what physical feelings you should have afterwords, but you go and get checked for any STD's or your mind will play all kinds of tricks on you.
Good luck!
It could be a bacterial infection of the urethra which can happen overnight. It does not have to be an std but you are getting checked which is good. Drink Cranberry Juice as it can help.
It could be a yeast infection at the most. It isn't likely anything huge if the symptoms pop up that quick.
