Could I be pregnant?

I began my period on the 29th of December, 2016 and it finished on the 4th of January, 2017. My boyfriend and I had sex on the 9th of January (using a condom), and I'm now on cycle day 40 (8 days late). I did start eating quite healthy this year, and waking up about 2 hours earlier, and I've just gone back to school so I'm stressed to say the least, I also stop taking The Pill late December. Please any advice would be helpful!
