positive OPK but no CM!! ☹️😔

Brooke
I got a positive ovulation test Friday, 7:30 a.m. My hubby and I BD at noon on Friday and used preseed. I was crampy, so I assume I ovulated Friday. By Saturday, completely dry!! No CM. What does this mean? We couldn't even BD Saturday because it was soooo dry and no more Preseed.
