Could I be pregnant?!

Kaitlyn

Does anyone know if the mini pill (progesterone only) is effective as soon as you start a new pack if you started it late. I started my new pack 5 days late and my app is now saying I am in my fertile phase. I am now on pill 6 so am I protected and could I have ovulated last week, the week I didn’t take it even though I “should” be ovulating this week??
