Really, please stay focused. You had safe sex. HIV is not (NOT, N-O-T) diagnosed by symptoms. Ever. You are concocting scenarios that are not real life. You do not have HIV. You do not need to test. Nothing else you add or worry about will change that answer.
She didn't use a fake condom. You are freaking yourself out. You had protected sex which is SAFE sex. Try to relax and don't let your anxiety get out of hand here. Think rationally. You were so safe that you don't need to test.
could i have caught anothe STD from her instead as I have a feeling of ants crawling over me tonight (itchy feeling but not rash or redness). But I wore a condom so I cant have caught any STD no?
She only used the condo to protect herself from you, so why would she use one that put herself at risk?
You used a condom so can't have HIV and have a medical diagnosis of conjunctivitis, so nothing else to say.
