Did I ovulate yesterday?

Ha

I have been bad about tracking everything else except my BBT and LH tests. I don’t sleep well so I don’t know if BBT will work for me but this is the first cycle I tried it. I usually get a higher LH result in the morning than in the afternoon but on CD 12 I took the test later than usual, would I have gotten a positive if I took it earlier?

Should I assume I ovulated or keep testing?
