Should I Worry?!

I am on the pill but <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> said my period was supposed to start Wednesday as usual.

It hasn’t.

Should I go ahead and take a test?!

I’ve not missed the pill or take antibiotics or any other concern for birth control. So now the answer is to wait it out or take a test?

Update! Negative test and my period started 7 days late
