TTC ovulation test

Here me out here.

So we’ve had our wedding moved again. We sat down and decided we would ttc with no pressure. However my partner ordered an ovulation testing kit(I’m happy with this btw)

I have started using this, not had any positives as of yet (cycle day 11).

On average my cycles are 25/26 long.

I’ve had a little cm today but had negative test this morning.

This is my first time using this- just trying to find out on what cycle days positives were likely ?
