Just bought a pack of clear blue digital OPKs yesterday and I got my first smiley face giving me the green light for baby dancing! I've used the line OPKs for about two months prior to TTC to try and get a feel for my cycle but I think they really just confused me more than anything. Plus if you really want to see the line on the digital one you can! First time user and I'm definitely loving them! Do you guys have a preference? ​​
