Fertility question

BeautyMommy • Have two little girls alive in this world. One I adopted out. Very hard decision. Plan on having more soon but for now, Trying hard to better myself and my life so I can give my children the world.
My period was late and short this month, throwing all my tracking out of whack. According to glow there's a full 8 days between my last AF day to my first fertile day. That seems like a lot to me and doesn't seem right. On top of that my CM isn't normal for ovulation. I'm wondering could I have skipped ovulation this month or is glow wrong and could have taken place last week. Anybody?
