Hi,
I've been ttc for a few years, and have been monitoring bbt for around a year- my bbt always drops just before af. My af arrived 11dpo and my temps looked like they were starting to drop but day 2 of af they have risen to a higher temp than any other time in my cycle and have stayed up for 2 days. I tested to be sure and bfn. Has anyone had unusual temps during af?
