can precum in saliva make you pregnant?

Please help... this happened yesterday so things got heated up and he told me he was using his left hand the whole time for himself and using his right hand to finger me. But I’m really concerned because I went down there to lick off the pre cum then we were making out for a bit(I know it’s gross) then he spat on his fingers to wet them up a bit. Before this happened, around an hour or so he went down to my vagina and licked down there. He told me everything he tried to finger me his fingers wouldn’t be wet anymore. I’m just really concerned if precum in mouth and exchanging saliva can make you pregnant. I’m just 15 please please someone reply fast
