HELLLLLLPPPPP

Every since I’ve used this app it’s been spot on when I was going to start maybe like a day early or day later but that’s usually it. But this month it says I’m 7 days late and there’s only one more week left in this month and I have no symptoms of starting my period any time soon like I normally do. What is going on????? I know everyone is gonna say “you’re pregnant.” But I’ve always had unprotected sex (pullout method) for 7 years with the same man I don’t see that being possible this month... we’ve barely slept together if like maybe twice this month. (We work different schedules😅) but should I take a test for peace of mind? What would you do??
