3 days pos opk

Danielle • Mommy of 3 girls ages 12, 6 and 4

I never seen this and I’m not pregnant . 4 or 5 days ago I took a Clearblue and got flashing smiley and 4 days ago I got a solid smiley but negative on these . I got my first positive opk cd 18 but they are still positive 3 days later . Is this normal ? When have I ovulated then ? Temp chart below too. Yesterday I had the worse ovulation pain.
