When it says your period should start but it hasn't shown

Question

Humm.. Is the app wrong then? Why does it say my period should start when I never got my period

Strange

Answer

It's just a prediction based on your previous cycles

Answer

It predicts your period based on the rule that after you ovulate your period will start 14 to 16 days later. 
If your period is "late" it means you ovulated late.

Answer

Ohh so it's not really actuate

Answer

The more you log the more accurate it gets.   If you are irregular it takes a while for it to catch up with you.   I would test 3 days after missed period.
