Clearblue ovulation test questions??!

I have been getting blinking smiley faces for four days now which means high fertility.  I thought you would only get blinking faces for two days then peak smiley face. Did anyone else have this issue?  This is my first month trying this type of opk. We have been trying for #2 now for a year, had a chemical pregnancy in April, and now I am on a fertility medicine since my progesterone was a little low. Just super frustrated!
