Does anybody use Clearblue advanced ovulation tests?

I’ve had ‘high’ fertility since Friday (6 days now) but not had a ‘peak’. Am I out this month?

I didn’t have a proper period, just spotting for 5 days (I’m usually on medication due to how heavy they are) and got 2 false positives, but the more expensive tests showed negative over the course of a week.

I’m on CD23 since the spotting which I’m now classing as a light period 🤷🏻‍♀️
