Do you find that you are getting the positive with your kit around the same cycle day each month? If so, keep in mind you can have intercourse up to a few days before--the important thing is that the sperm is there ready for the egg at ovulation. So, it might be wise not to wait so long and try to have intercourse a little sooner before ovulation so you aren't too late.
As I had said, we were successful on day 10, and I probably didn't ovulate until day 12 or 13.... And to be honest, we did it on that day because my hubby was going on a trip right after, and he didn't know that day was chosen for any specific reason...he just figured we were having sex to have sex

Though he knew we were trying to TTC, I never really discussed the good days with him or anything like that. I just really tried to make it no big deal.
