I'm late!!

Shana
I am currently 4 days late! We have been TTC for about 2 months so, still new at this! I have been on the skyla for over 2 years and I had a period when I got off towards the end of May. I was supposed to start my period (per the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a>) 4 days ago. I never had a period when I was on the skyla so I'm not sure if I'm a regular cycler or not lol before the skyla I was on BC so, that was timed also. So, should I take a pregnancy test? Or should I wait a couple more weeks? Is it too soon to take it since I'm only 4 days late?
