Negative blood but...

Posted in another group, so sorry for spam. Just trying to get different views. I haven’t had a period since my last one on June 28th. I’ve taken test after test and all showed a faint positive especially in the afternoon even after my urine is diluted. The catch is my blood test was negative 2 weeks ago but I just took another test this evening and it was faint positive again. The lines aren’t getting darker they are at a stand still. I have not bled yet at all. Not even spotting...... anybody got a clue what may be going on?

Tests below (first one from today). These are all different tests
