Clear Blue Advance says positive and First Response says negative?
So yesterday I posted because my First Response line was getting lighter and I got my first blinking smiley on Clear Blue. This morning I had a solid smiley face! (I've been using CB for 3 months and have never gotten a solid smiley) So to verify I used one of my First Response ovulation tests and there wasn't even a line...what is going on?
