I've had regular 26 day cycles for the past 10 years and ovulated on cd11 for the past 6 months (confirmed with opk, bbt charting and ov pains). I conceived this year on cd11 so know that it works for me.
Last month I ovulated on cd10 but still had a 26 day cycle as my luteal phase was a day longer than usual (it's normally 14 days).
Then this month I ovulated on cd9.
Does anyone else have a short follicular phase or ovulated earlier than usual? Or does anyone know why my follicular phase would decrease and my luteal phase increase? Or has anyone conceived as early as cd9?
