Pregnancy chances

Ha
What are the chances of me getting pregnant when my period is suppose to come in a few days?
My boyfriend and I had sex during my window, after my window, and then last night. We stopped using protection, but what are the chances? 
I've taken a pregnancy test this past week because I was sick all day, but it was just a bug. My boobs haven't been killer, but a little on the sore side, and my period is getting closer so I'm starting to get pms symptoms. 
The wait has been a dang struggle. I just want to know!
