Positive followed by negatives...:( Advice?

I just don’t understand :( top 12 DPO, middle 13 DPO and bottom today 14 DPO. Top was faint blue in 1 minute of taking, so not an evap from sitting:( am I out? What does a VFL to 2 negatives mean?

I’m currently CD 31, and 4th round of clomid..I was feeling so so so hopeful this cycle because I had my first dominant follicle, tracked by digital opk, BD several days in fertile window and held my legs up for 30 min after each time.

I can’t help but feel like I did something wrong.
