Last year, February, I had chlymadia from a random hookup but was immediately clear. During that time i was starting a relationship with a girl who im still on and off with. Back in September, 2018, i had a full std screening, hep c, hiv, hsv1/2 chlamydia, gonorrhea and syphilis. i was negative for all. My question is, even though im negative I have a silly worry that i gave my partner something. She has seen my papers and knows im clear. Should i be worried I gave her something?
