Condom and Plan B (5 stars best answer)?

I had with a friend of mine. We used a condom and there was no breakage. I pulled out after , gripping the base of the condom. I'm most likely being paranoid, but I did feel wetness while pulling out. It should have been her wetness and not sperm, as I used a condom. I kinda freaked out and bought her a Plan B pill which she took 10 hours after we had . Should I be worried about her getting pregnant? I'm a 24 year old male so I don't need stupid answers or rudeness.
