Fingered and pregnant??

If someone could please help me. Yesterday my boyfriend fingered me and then I decided for the first time to give him a hand job but it only last for like 15 seconds Bc it was my first time and I got nervous. After that he adjusted his penis and then about 4 minutes later he fingered me again but we had clothes on we were just going under the clothes. He doesn’t remember is he had anything on him but is there any chance of pregnancy. (I’m a virgin)
