Could I be pregnant?

I haven't had any symptoms except for the fact that my period is late (according to glow). Sometimes my period doesn't always come on the day glow suggests but it suggested that my period was supposed to come Jan 10. Today is jan 13. It still hasn't came. Last month it started jan 15, & usually comes towards the end of the month so im thinking that's when it's going to come. Im on BC pills (im on my last week) which means it should come sometime this week but I had unprotected sex jan 7 & 8. But my bf pulled out. Im still worried . Is it too early to tell if I'm pregnant?
