Is this normal ? I’m so confused

Grace

So my period is supposed to come October 3

I’m confused about the ovulation strips . I’ve been pregnant this August I had a miscarriage I was 6 weeks, and I don’t know. The first one I Just took this morning. Please help me . Is this normal for strips to do this before your period . And yes I have had sex around when the app said I was ovulating. I think I might be pregnant .
