I wish I could help, but I've got no idea rai (sorry!) - I didn't know progesterone could be negative though!

Sorry I haven't come in and updated lately.
DS never got his 18 month appt, the CHN was sick and I got called as we were on the way that it was cancelled. Apparently they're going to reschedule but that was 2 weeks ago they said that.
AFM, I definitely think I O'ed this time, especially with all the EWCM (just look at my chart!) and the definitive positive OPKs I had (though I should learn my lesson from last time!) but don't know where exactly I am in the TWW. I never got to go for my CD21 BT on CD21, but I'll probably go for it next week sometime (when I THINK I'm on 7DPO)
