Should I be concerned?

I lost my virginity on January 4th, and my last period was on January 2nd. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> is saying I should have gotten my period yesterday, but I have no sign of changing discharge. I'm having horrible cramps, headaches, tender breasts, and I'm very bloated on and off. When I lost my virginity, he nor did I orgasm. Does my cherry popping have anything to do with my period being a little late? The sex was protected.
