FF verse Glo

Hi all. Below is my FF chart. My temp has been all over the place this month. It has been hot out, my room is upstairs, and even though we have a window AC I feel like my bbt has been suffering. I wake up feeling warmer than other times of the year. So I have not had a positive opk. CD 14 it was pretty dark, but definitely not positive. I also do not feel like I ovulated yet, and I am having watery CM. But FF has my ovulation a few days ago. What do you think?
