Dried cum on fingers wiped off waited for a minute then fingered my girlfriend

Hey! I may be over thinking this but Im stressing out. Me and my girl friend had sex just a few hours ago. I used a condom. After I ejaculated I went to the rest room and took the condom off. I then noticed my penis head was a bit wet so I wiped it off with some toilet paper. I then rinsed and lightly soaped off my hands. After that i then touched my penis head again to remove some toilet paper from it. about 3-5 minutes later I fingered my girlfriend. Is there any chance of her getting pregnant through this? If so what are the chances. she would just take plan b to be sure but she has in the past and does not react well to it. Help me!!!
