Can she be pregnant after fingering?

Me and my girl decided to 'play' around last night, the 23rd of January. So we were kissing, then feeling and a couple hours later we were having sex, with a condom of course. well we were actually having sex for maybe 10 minutes and she says "oh wait, I don't want a urinary tract infection, let me go pee" and she left the room for maybe 2 minutes max. Well I didn't think about it then but I know if you lose the 'boner' in a condom somehow the condom can become ineffective. I couldn't get it hard enough to stay in her because she was real tight and along with the peeing incident, my cat jumped on the bed and someone called both our phones. so we decided to just end it and i took the condom off. we made out and she gave me a ********. then I fingered her. now I'm wondering if it is realistically possible that I got enough pre-*** on my fingers while taking the condom off (I didn't ejaculate in it) to get her pregnant while fingering her? Her period ended 3 or 4 days before we had sex, I know for a fact the condom didn't break, she is going to take Plan B Tomorrow, less than 48 hours after the incident, and again there was just pre-*** in the condom. should we be in the clear? This is gonna be a long three weeks... Help!?!?!?
