Positive then negative?

So I’ve been testing for a couple days now since there has been no sign of AF!

The first test I took was when I was four days late, and I got a very very extremely light positive.

I then test when I’m nine days late with first morning using and it was still light but way more obvious that it was more of a positive.

Just to double check I took another test the following morning (10 days late) and it’s way more light. It wasn’t technically first morning urine so not sure if that’s why. I hardly see a line. If anything it’s extremely faint.

Has anyone experienced this? Should I keep testing and freaking myself out? Lol
