App problem

Maira • Sup. 🦊

Um... it told me to tell the app when my last period was and I didn’t remember but it wouldn’t let me skip that step and now it’s saying I’m 10 days late I have a 9% chance of pregnancy but I’ve never had sex or a make out session, usually due to my chemical and hormone imbalance it’s very unpredictable. How do I fix that? I doubt I’m 10 days late.
