Do you ovulate the same day each cycle?

Olivia

I’m confused. Just started tracking a few month ahead of TTC. Those months I ovulated cd16, tracked bbt and used opk. This month we started BD the day after my period ended. I’m now on CD14, I have not gotten a positive opk yet but my temp is showing I ovulated Friday. I also had ovulation bleeding sat/yesterday, which I’ve never had. Physically I have all the symptoms but test wise I don’t. What’s up??
