False negative ovulation?

Kay • Married 12|13|14. Together for 13 years. High school sweethearts.

I've usually had pretty good luck with OPK but for some reason it didn't work for me this month. Went to the dr for an ultrasound he said it looks like I ovulated but to wait for the blood work. Blood work comes back that I did ovulate but yet the tests were all negative for 12 days.....

Anyone else have this issue?

Hard to time intercourse when you don't know when you ovulate 😞

Hopefully it worked in my favor!
