My cycles vary in length and are typically quite long (30-50days). I know the exact day I ovulated this month (I had a positive opk CD19 so I think I ovulated the next day). This was the first month I used OPKS so a few months ago when I had a 32day cycle my app calculated I had probably ovulated on CD19. Would that suggest that this month it'll be 32days long? I hope that makes sense? Currently CD26 so 7dpo.
