i understand how ovulation tests work i dont need an explanation... but i just took an ovulation test today and last night and todays was a tad darker than last nights. And today I started getting some more cm that looked like the pic below. Would this mean that I’m in my fertile window and the lines should keep getting darker!? Ovulation in the next few days? Btw havent done anything sexual in 3 weeks. Since before my last period.
