I'm confused

Summer • 🍼02/06/19🍼 · 08/30/2024🍼

I'm 2-3 days late, I took a first response 2 days before my period was due & it had a faint second line. I took a clear blue digital today & it said not pregnant. I'm not sure if I should wait another day or 2 & try another test. I've never been late except for my first pregnancy, my periods are super regular. My symptoms are exhaustion, sore boobs, nausea, cramps(mild), headaches.. anyone have any thoughts?
