Hey Becca, if af showed later in the day I would say mark tomorrow as cd1, but by tomorrow morning when you set it, you will already have been bleeding for 20 hours! Thats close enough to a day I would think!

Thats just would I would do though. I agree with what Lori said about using whatever cycle day you are using for the clomid. Also ... If you wanted to try charting this cycle, fertility friend would mark today as cd1, I believe. I added charting to using my monitor because even using the monitor, it doesnt confirm ovulation, just lets you know you have surged. (The girl at customer service informed me of that!

) With charting, it cant predict O but it does confirm that you have O'ed once it sees the temperature shift. Its really not hard, if you want to give it a go!
