First time using Clearblue OPKs

Hi everyone! I just had a quick question. This is my first time using an ovulation test but my SO and I have been trying for a baby for years. This is my first cycle ever using this test and when I took it this morning the smiley face was blinking which according to the paper indicated high fertility. However, the test line is very light. Should I wait a few more days? Any and all help/suggestions are welcomed pretty please ☺️☺️ thank you!
