Can some tell that we have done enough pls ?

The OPKs let you know the is a surge and that Ovulation will may take place 12-24 hours after the positive OPK. As I'm sure you know semen can live up to 5 days so if you DTD 5 days ago and in the next 2 days you should be good to go pending this is your month. Good Luck and Baby Dust.
