Cd13 opk?? Please help y’all

Hey y’all so I’m on provera to start my cycle and letrozole 5mg days 2-7 and it’s days to bd days 10-17..

on cd13 and these opks I feel like aren’t getting ANY darker! I’m feeling light cramps on both sides today but trying not to get my hopes up with how these tests are looking. Anyone else get the same thing and still ovulate that month? It’s our last cycle before we have to go to a specialist and I’m soo worried they’ll deny us over my BMI and it will be all over. I’m really needing y’all’s help ):
