Help! Which ones are right??

These OPKs are in order top to bottom oldest to newest. I’m missing two of the blue ones from earlier in my cycle when they were definitely negative. The blue ones I think show a positive in 4/3 and now clearly fading. The pink ones look more positive now. What? Why are they different? I used the same little sample of urine to dip both in at the same time following directions. I just don’t know if ive ovulated or not.

Any words of wisdom would be appreciated. Thanks ladies!!!
