Pregnancy risk

Hi guys,

So I had sex with my boyfriend on the 6th day (Friday) of my Junel Fe period week pills (my period was over) and the condom broke. I wasn't sure if being on that week of my pills meant that I was not protected by my pills, so I took a Plan B One Step within an hour. I know this might seem like a stupid question, but is it likely that I could be pregnant?
