@donasmrs-- Unfortunately, I don't think anyone can help you here. You need to see a gynecologist about this.
Having no cervical mucus during ovulation does not mean that you are no ovulating. You might have fertile cervical mucus but it might be very little and difficult to notice. Cervical mucus does decrease with age. So if you are used to checking cervical mucus by wiping, you might have to check for mucus with your fingers from now on.
I highly recommend getting an ovulation kit first to check if you're ovulating or not. Or directly go to your gynecologist.
By the way, when did your mother enter menopause? If she entered menopause in her forties, you could be experiencing changes in cervical mucus due to perimenopause.
