Hey Ngala, I agree that you probably O'd on days 14 or 15 based on your signs and temps. Charting is hard with interrupted sleep and there are enough variables as it is!

I've used the same OPKs as you and have only had a 'true positive' once. I tend to count the OPK with the darkest line (even if it's half the width of the control e.g. first half is dark and then fades out) as a positive.

The signs you describe over the past few days sound like luteal phase to me. Go the progesterone!

Best of luck sweetpea.
