Is this a positive LH?

airhead

If not how soon should I test again? Yesterday the test line was so low I could barely see it. 24 hours later it’s way darker. Normally I peak on CD 15 and O CD 16 (lh strips go back to low reading by end of day cd16) today is only CD 12 for me so not sure why it’s this high this early. Also my first time ever using the equate brand LH tests. I normally use the Femometer strips. Any insights here?
