Does FF not give you cross hairs if you don't record any CM? I am pretty sure from my temperatures that I ovulated on Sunday (or thereabouts) but FF hasn't given me crosshairs. I have had a very "dry" month, probably due to dehydration (I had a cold at the start of the month, which can apparently cause dryness and then food poisoning over the weekend which obviously can dehydrate). So I haven't entered any CM because I didn't see any of note. And my OPKs all showed negative but I was testing at strange times over the weekend due to travelling (they did detect a small amount of LH Friday/Saturday/Sunday but no surge and were showing no LH by Monday).
If anyone wants to have a go at chart interpretation and tell me what they think my chart is here: www.fertilityfriend.com/home/343af6
Annoyingly, it matters this month because I need to get my 7dpo progesterone test done (I have already postponed it one month because it last fell in the middle of one of April's 4 day weekends). I think I will be 7dpo on Sunday (in the middle of another long weekend!) so Friday at 5 days dpo is probably my best bet.
