can you get pregnant?

I took a plan B for having unprotected sex. But I believe there are other things we did that could/couldn't get me pregnant. Here's the run down 
1. Sex (with condom)
2. Sex in shower (with condom) 
3. Sex again (when condom got stuck inside me) 
He didn't cum in me, but could he have gotten me pregnant with precum even though it was exposed to water? (Btw the condom never broke, even after water exposure) it just slipped off inside me.
