Clearblue Advanced Results-Help!

Lindsay
This is my third month using Clearblue Advanced to track my ovulation and my second month using Chlomid.
I have had a blinking smiley (high fertility) for 7 days in a row! Is this odd? Should I be concerned? I test first thing in the morning and have followed all of the instructions. It was fairly simple the first one I used it (2 days blinking smiley, 48 hours solid smiley).
Anyone else experiencing this?
