I had strep for a couple weeks without knowing it, later getting some blood tests done that came back positive. All that time before, I had been kissing my boyfriend, and now I worry that I might've given it to him since it's super contagious. He hasn't had any symptoms though (this is like 2 weeks later), and that's different from me because I had all kinds of things happening; just didn't know it was strep. I've finished my antibiotics, and now I'm wondering if it would be safe to kiss again, or if he might have it and I'd just catch it again?
