No temp rise after ovulation?


Glow has been spot on for the date of my ovulation. I always have a temperature rise the day after glow predicts I ovulate. I am a diligent temp taker and always take at the same time In the AM before I get up Etc. Yesterday I would have ovulated and today I should have had my temp rise. No rise today in fact it’s the same as yesterday. My CM hasn’t been very accurate either but I think it’s because I haven’t been drinking much water (coffee and wine because of the holidays!)

I also did a OPK which had a positive on the 24th. Is it possible that I ovulate today, a day later than predicted?
