So my husband and I have been ttc for 3 months now so we decided we wanted to try using opks

I took my first opk the day after my period and this is what it looked like (CD8)

Then I took one CD 9

And then cd 10 this morning 12 AM so we baby danced as soon as we saw the positive AND THEN THE MORNING OF AT 10 AM AND IT WAS NEGATIVE???

As you can see my LH says at 12am it’s a 62-87 but at 10 am LH is 16?

I am really confused because I always though I always thought I ovulated later in my cycle around CD 18-20

Did we Baby dance too late? Please help.
