Did I just skip my period????! HELP!

Nina • 29, TTC baby #1, madly in love
Did I just SKIP my period??
 Glow says my period was due on Thursday, it is now SUNDAY and AF is not here.  TMI, but we had sex once on Day 1 of my fertile window and a few other times but DH never fully released -- he/we were just too tired.
​Could I be pregnant?? Thought we were out because we had sex too early before peak O day (although still in fertile window according to Glow). 
​What gives?????? No symptoms, really.  Could it be???  Did I just skip a month (never happens)??
