First response early detection tests taken at 10dpo and 11dpo, faint lines but positive nonetheless yes?

Clear blue early detection taken at 12dpo, faint but much clearer and definitely there.

Clear blue early detection taken today at 13dpo, first morning wee accompanies with a nice smear of red cm on the tissue paper? Where has my line gone, I’m heartbroken what is going on??

Surely 3 positives can’t be followed by such an abrupt negative.

AF is due tomorrow but I’ve given up hope now, I feel terrible. My partner was so excited I don’t even want to continue this day, just want to curl into a ball.
