Yes, the chances are low. Probably close to nonexistent.
I guess I should clarify why I ask this question. Two days ago I got this tiny little sore type thing it was on the outside of my lip, it didnt behave like a cold sore and by that night had started scabbing over and clearing up.
My partner and I had sex and oral sex the next morning. Later during the day I noticed it was a bit larger than it had been the day before but scabbed over so wondering what the chances are it was a cold sore, if it was how contagious was it and the likelyhood that I passed it onto him.
The incubation period is up to 2 weeks is that correct?
