Confused HELP!

Dzenana

So I took femara 5mg cd 5-9 and I am suppose to be 4 days away from my period but I just got this for an opk ... I did blood work on day 23 at my ob’s office and they said I didn’t ovulate and to come back Friday (today) to do another round of blood work to see if I’m nearing ovulation... well I just got this opk. Is this positive? I’m cd 26 so this is very off to me. I usually ovulate around day 17
