Anyone's tests go up and down like this?

I am so baffled. My cycle is between 30-35 days. I have PCOS and sometimes go longer, but the last 3 months have been consistent.
These tests are from CD 9 thru today, which is CD 18.
Is it normal to fluctuate so much? I'm afraid I'm going to go back to longer periods :/

Yes mine were all over the place lol. It could literally go from nearly blank to positive overnight lol.
