Dreaded POS

Of

Ok so I’ve posted a progression of my POS here....however I took one today, 23 dpo, 5.2 weeks pregnant and it’s much lighter, however I never did have one that was darker than the control. Please share stories of your experiences with tests? Just looking for reassurance or info, and yes it’s ok to say that “it doesn’t look good” and yes it’s ok to tell me to stop taking them lol. First apt. 9/27/18. No beta taken yet, praying for rainbow baby to stick until May/19. Is the “HCG Hook effect” possibly to blame here? Thanks for reading!!!!
