Could I be pregnant?

Mg
My bf and I started trying to conceive feb. I'm 34 and my period is two days late. I started  tracking my periods on the app in December and for the most part it's very accurate I'm regular every 28 days. According to the app I  was supposed to start my period two days ago. I don't feel different I'm not sure if it's to early to take a pregnancy test ? Any advice ??
