A member asked:

I had a 48 hours lh surge with clear blue digital opks and sticks positive when did i o during surge or after ? am just trying to know me, thanks.

After surge.: You ovulate about 36 hours after the surge. When you are surging, though, you are fertile because higher levels of estrogen are making the cervical mucous thin, and sperm can live 2-3 days ( or longer) in good mucous.
