So I normally have used the clearblue ovulation kit, this month I tried the advanced thinking it'll give me more information. However it still has not detected anything, no peak or high. I use glow and ovia to track and both weeks they predicted have past. Also two days ago I had eggwhite cm so I thought I would get a peak. Did I just totally miss my window or is it possible to not ovulate? Or does the kit sometime not pick up it?
