Ovulation window

Eva • Wed, Feb 27 • Momma to Gracelynn brooks and a little baby in heaven✨ With the man of my dreams for 8 years🖤

So I have been using ovulation tests to track my cycle as most do, but I have been getting positive ovulation tests since Sunday morning. As of today, I am still getting a positive test.

Is it possible to have LH surges that long? Sunday morning to Wednesday morning?
