Chances of being preg?

I’ve just started my fertile days (day one) and yesterday i was w my boyfriend we didn’t do anything but he put his finger in me for only a second. I don’t think there was anything on his hands but if there was it would’ve been dried precum (bc there was no semen at all) helpppp

(Im also starting mini pill today so i don’t think I’ll be able to check for a period)
