Cb advanced opk alternating between negative and positive

[DobbyForever]

Just curious if anybody has had this. My fmu pops up close to positive but negative, smu is positive (but not the strong middle of the surge positive where my line is double or triple as dark as the control), then afternoon is negative.... This has happened yesterday and today. I'm not cramping but I had flutters yesterday. My temp this morning is unreliable because I was tossing and turning and did not get consistent good sleep and I had a cocktail last night. Just scared I am going to end up anovulatory again

The only other time something similar happened i had one day of this then went on to have a major, dark surge that lasted over a week and ended anovulatory.
