so I've been using the clearblue advanced digital ovulation tests and have been testing every morning as it says on the box. 5 days ago I got a blinking smiley, after that I've also been using lh strips. I had what looked pretty positive a few days ago but never got a solid smiley on the digital test. I just did the digital and lh strip and the digital gave me a blinking smiley and the lh strip was a clear negative. since I had a pretty clear positive does that mean I've had my lh surge already?
