I would try to BD tonight and tomorrow and or the next day. From what I've read and understand, you don't ovulate right when you get the positive. I have read that most women usually release the egg in a day or two after a positive opk?
Last cycle I had a positive opk and all the signs of ovulation, we dtd that night and I don't think we dtd for 2 or 3 days. Well.. I'm not pregnant so I didn't do something right!
But anyway, that's how I understand it unless someone else knows differently?
