babyjosh,
For me, i BD the moment my monitor indicate peak (+ve). i tink tats juz nice to catch a girl ba... cos opk shld be able to detect O within 24-48hrs and O will stay for another 24hrs.
if wanna a girl, can try to BD couple of days before ur supposely O. "x" sperm can live for up to 5 days, but "y" sperm can only live for 1 day. so i tink u can happily BD till detect O, then stop.
