5 days late, cramps, feeling tired

I’m 5 days late, have period-like cramps, heartburn, I’m tired, but not overly tired, and I’m feeling bloated. I took a test the day I was due for AF and it was negative. It’s now 5 days late and I think I’m waiting for a couple more days to retest. Looking back, I didn’t see two lines, but I just tried this negative photo app and I do t know if I have “line eyes” but I kind of see a fffl. Does anyone else see it or am I crazy?
