Lanfear-Does your app say you o'd? Can you put your chart in your signature so we can all see it? Also..I would keep using the OPKs. FFoe often wants to give crosshairs, but since it's your first month, the program doesn't know anything about you and hasn't established a pattern. Get BD'ing just in case. Every other day at this point should do, so you have some reserves.
I would say your temps are really low to have Od but thats just my guess FF probably figured u Od cuz u put C CM that's a sign of past ovulation !! GL
Glad to hear sounds like u got a Lot of BD in so u should be good u shouldn't actually O until 36 hrs or so after the +++ OPK!! GL
