Faint line???

Hello everyone.

I was supposed to get my period on July 23 I didn't get it then on the 26th I was spotting so I thought I was getting it but the next day nothing later on in the night I went to use the rr and when I wiped there was spotting again later that night wiped then nothing. This went on for about a week. So I'm not exactly sure what's happening here. I don't miss a month I'm regular. The app says I'm 34 days late and I took tests came back negative. I looked online and it said that I checked late. I've been experiencing symptoms like sore breasts, headaches, nausea and more.
