Can precum get me pregnant?

My boyfriend and I took a shower together and his penis was erect and I saw some clear fluid coming out of his penis which I assume is precum. He washed it with water and fingered me right away. Now I’m afraid he had precum on his fingers when he fingered me.

I’ve been stressing this out for 2 weeks now even though I’m on combination birth control pills for a year. I’m on my placebo week now and I usually get my period the in between the 5th and 7th day of my placebo pills. What if I don’t get my period? Could I be pregnant?
