can sperm survive in saliva?

My period ended Mon April 2 and me and my husband had sex both on the first and second of April without a condom. He pulled out of course, and yesterday April 4 we had sex again but he ejaculated in my mouth and when i spit it out some got onto his fingers and he put his fingers inside me. So is it possible for me to get pregnant?He inserted his fingers right after so it didn't dry or anything. I also took fertility test today and its positive. I was told saliva kills sperm but I've also been told it can survive as long as it does not dry. Also i missed my bc pill last night to so are the odds greater i could be pregnant?
