I'm charting my first cycle since a missed miscarriage and two surgeries. The bleeding after the second surgery seemed to roll straight into period so marking cd 1 was a bit of a rough estimate. FF can't make up it's mind about ovulation. Atm says ovulated cd 25, but it has also told me cd 14 and cd 21. I'm also wondering if maybe this month is just an anovulatory cycle. Any ideas? My charts pre-miscarriage were always fairly clear, always had obvious pre and post ovulation temps that you could see visually without the FF cover line.
