High fertility after ovulation?

Mary
Please someone help. I am going crazy. My cervix has been high for a few days after going to medium height after ovulation. Then I just tested with clear blue digital and got high fertility? What do you think? I am so confused. I have been cramping the last two days (but I did cramp near ovulation). I'm 5dpo (supposedly ovulated last Friday) and don't know what to think. Any advice would greatly be appreciated!
