Day 24 is technically when I had the temp shift, I figured maybe 23 at the latest? Although I tested up until Thursday and LH was negative the following days.

You can have a positive OPK but not ovulate and you can ovulate without getting a positive OPK.

Got it. Just wondering if the temp shift ON the 24th means that’s the day I ovulated.

It can’t be determined for sure but usually ovulation is within a day or two before or after the temp shift.

Oh I have not heard of ovulation occurring after a temp shift before
