Opk Question

Hello ladies! I have a question about my opk and ovulation. I got my peak yesterday afternoon, but I am still getting high readings. I know that the LH surge can last 24 hours but I was wondering if that means I ovulated yesterday or today? I am also trying my hand at temping but I wont know till after on that (plus not 100% my thermometer is working great, temp this morning was 96.72 which seems really low).

We have been trying for several months and I want to make sure I get the timing down right.

Thank you for taking the time to read, I really appreciate any input or advice.
