Scared that im pregnant

First of all im bad at english. And i have no experience about using ovulation control apps. Just wanted to know that my period started 5th of Nov and i had sex wth my bf right at the end of my period 10th with no protection. And now im scared that if im pregnant. How soon can i check with pergnancy test or is it ok? Any risks? Please help me if you have experienced any situations like this
