Crazy OPKs - have I even ovulated?

Jennifer

Flow predicted i would ovulate on 1st August but it was off by 2 days last month so wasn’t surprised when OPK came back neg still.

OPK then showed a very strong, almost positive on 2nd August but then got weaker throughout the day.

The same thing happened yesterday (3rd August) but now is weaker again today.

Has this happened to anyone else? Have I even ovulated? So frustrating because I don’t know when is best to do the dance. TIA.
