Opk confusion

Nicole • baby #3 for me, but baby #1 for daddy. We are so excited!!
Last week I tested positive for like 4 days. Then a few days of negatives now its really positive again, darker than the control line.. Not sure what this means?? I'm confused. Any insights would greatly help. I will post pictures of the newest one and ones from over a week ago. (The one with 2 is from over a week ago, the one with 1 is today) (negative hgh)
