I think I ovulated last night with temp and OPK. DH comes to bed very late, and we typically BD in the middle of the night when he comes to bed. Last night it was about 3am. Usually I just put an X, but around O I try to be more exact. So, for middle of the night BD, do you put last night pm or this day am?
Everyone does it differently, but if it were me, I would put AM since it's closer to dawn. Hope you caught the egg!
