No as I usually ovulate anywhere from day 19-23 as I have longer cycles
I just would assume you where more hydrated than you thought for the stray lower tests.
You could just be ovulating later this cycle
Could be that your body is trying to ovulate and didn’t manage it the first time, or it’s possible to actually ovulate more than once (maybe you’ll end up with twins) it’s honestly hard to tell but I probably wouldn’t worry about it unless the next cycle is like this too. Then I’d start wondering what might have changed to mess with your hormones
If you was to be pregnant would it definitely show yet on a test?
