My friend had sex with someone and got Chlamydia from it 3 weeks later she got blood tests that showed positive for it (Valentines day weekend). Its been ~35 days now since she had sex. Her and I have kissed a few times and shared saliva during some of those times. I didn't know she had it till today, when I asked her what her test results were. Would I be at risk of catching it also? If so I will get blood tests and stuff.
