4 days late but I'm still testing negative

I have multiple apps and have not tried tracking ovulation yet and I'm getting really frustrated.

Every app says I'm late by 2-5 days

I took a dollar general test yesterday and it was negative, today I got 2 FRER tests and they both came out negative.

I don't feel like I usually do when I'm going to get my period and I'm having symptoms and feelings very similar to my last pregnancy.

I've been getting hot flashes like I did when I was pregnant, I've been feeling nauseous, tired, and a lot of indigestion symptoms.

Also my cervix clued me in to my last pregnancy, when my period was due it was closed high and extremely soft. It feels the exact same way now.

By all means I *feel* pregnant this month, but I'm still testing negative??

I'm gonna wait until tomorrow morning to test again, the other tests where taken later in the morning or early afternoon and weren't the first urine of the day so maybe that's the issue but 4 days late I was under the impression that it would show positive any time of day if it was??
