- Ok, that Jing link is working for me. The OPKs and CM do seem to support O on the 20th, and then you had a fallback rise, which I often have. Otherwise, as Lauren just said, you could have O'd on the 22nd, which would make you 10DPO and not unusual to get a BFN.
I personally have lost a lot of faith in OPKs after I got no hint of a line the day before I O'd this month, which just seemed odd since I was starting to feel O pain and knew for a fact I was about to O.
FF does seem to rely a lot on CM and those OPKs. For example, my chart shows a dotted line for O because of that negative OPK. My point is that if you took out the negative and put in a couple more days of EWCM (not advocating messing with your chart but thinking if you thought
you'd O'd already and stopped paying attention to your CM, maybe it was more EW than you realized) FF might very well change your O date.
All that being said, I think it's hard to tell, especially without the benefit of an earlier chart or two to compare to. I'm afraid you're gonna have to see what tomorrow's temp does. Good luck though!
