I Think I Am Pregnant But Not 100% Sure. I

I think I am pregnant but not 100% sure. I had sex on August 31, 2015. I missed a week of my birth control. Was suppose to start the next pack on August 26 but didn't. The birth control I take is Alysen (don't know it off hand) and it's a 28. Could there be a possibility that I could be pregnant? Would it be to soon to take a home pregnancy test? I'm also still taking my birth control incase I'm not.
