I wish there was a way to exclude certain cycles from what glow uses to predict upcoming fertile days etc. I have about 3 non-ovulatory 80 day "cycles" where I had to induce the period with medication. Obviously, these are not normal or helpful to predicting future cycles. I also wish that for those of us who use OPKs to predict ovulation rather than temping (insomnia plus toddler means not an option) fertile days would adjust based on a positive opk.
