Is it possible I tried then failed to Ovulate?

This is my first month charting so I am very new to all this, I am not using a BBT thermometer just a fever one. My cycles are fairly normal ranging from 26 to 30 days with average being 27. This cycle I used OPK which showed a positive and true positive on CD 14 and 15, had cramping but never saw a shift in temperature until today CD 20. Playing around with ff if I have two more days with high temps it would calculate my o day as CD16. Because I'm still new to this I started using OPKs again just to be sure and tonight I got a "high fertile" response. I'm not sure what to think of this alongside with my temps, any thought.

Hey hun! :wave: I would say that looking at your chart you geared up to ovulate but either haven't yet, or just did between cd 19 when you got the negative and cd20. I would make sure to BD! Good luck, and maybe get yourself a bbt thermometer if you are planning on charting, just for accuracy
