Missed period then sex

Kaitlyn
Hey so i need a little help. I have been tracking my period on glow and I was supposed to start my period on the 1st but that would have been day 25 of my cycle. I usually start my period between 25 and 28 days. So on the night of the 28 day I had unprotected sex and he pulled out and never came in side (in fact he had to jerk of a little before he actually came) so now on day 30 I still have not had my period and I'm a little concerned. Idk if I should take the morning after pill or if I should just wait until my period or what I just don't what to do please help
