HIV Scare

So I had sex with this guy I barley knew and he has two kids we didn't use protection and now I'm scared he gave me hiv or something I have no symptoms it's been like almost 5-6 weeks from now. He told me back then he was on drugs and he knows I'm scared I was asking him all kinds of crazy questions he said I'm starting to make him flip out I was like I'm sorry I'm just so OCD about not using protection which I messed  up 😔 I never made this mistake before but he told me a lot of times he don't have nothing... anyways what I'm trying to say has anybody ever felt scared they had HIV ? I stopped talking to him blocked him from everything so he tried to follow my ex best friend on Instagram and I guess he is trying to get information why I blocked him from everything plus I'm talking to somebody new now too
