I'm wondering if this is possible. I'm still BF and just had AF return earlier this month (Dec 7th). I have been charting temps and using an ovulation microscope. On CD 13 I had the temp drop, ferning on the microscope, temp rise on CD 14 (still ferning on the microscope) as well as spotting for 3 days CD 13-15. Then just last night (CD 22!) I had pains like O pains and when I took my temp this morning it dropped again (slightly lower than on CD 13). I pulled out the microscope again (I had put it away for this month thinking I had already O'd) and I see the ferning pattern again. What? Is this possible or do you think things are just still really messed up due to BF?
