Did I ovulate early??

According to glow I am supposed to ovulate in 3 days. I have been taking ovulation tests for about a week or so. All are negative however they seem to be getting more faint each day. Did I ovulate early and miss the window? How many days does it start to get darker and darker before getting the lh surge positive? Hopeful I didn’t miss the window. :(
