I've been getting neg on all my opk's and last night and today I've had a lot of dull pain and cramping and I've had to change my underwear twice already because I was that damp (sorry for tmi)! Could I b ovulating and it not showing up on my opk's? And should I update my log to show I'm ovulating?
