Sooooo last month I had the faintest positive

Then I had bleeding which came around the day of when my period was ment to be tested again and got the darkest positive then it slowly faded to nothing.

I then got a positive on an opk and bd around all my fertile days.

Two days ago I took another test because I had similar feelings to before but tested negative

so today still feeling weird I took another test which came back as this

What is going on should I be getting excited?
