Before anything else... I’m on the pill for a year and 2 months already, but ever since I started having sex I always make the guy wear a condom just to be sure.

Anyway, I’m kinda worried because I was little tipsy and I remembered that I had sex with a guy last night and I think when he fingered me he had cum on his hands. Let’s say he got some cum inside me, would there be a chance that I could get pregnant even if I’m on the pill? Should I take plan B? Again, I’m on the pill for a year and 2 months.
