Hello. I chart my BBT and CM on Fertility Friend and it seems I ovulated three days later than usual this month (on day 18). My luteal phase is always 13 days. My usual cycles are 27 days long but a late ov this month would surely mean my cycle will be 30 days instead. This means my expected period would now be Sunday but FF still has it down as Thursday. Can I change the expected date on the app myself?
