So confused. Clearblue OT

Ive recently started taking the clearblue ovulation test. I've gotten flashing smileys for the last few days, but no solid smiley. I thought after 2 days, a sold smiley was supposed to happen. Is this common? I'm so confused. 
My period is pretty irregular, and it's hard to track my cycle at all. I was hoping this test would help, but now I'm not so sure. Maybe I just have high levels of hormones all the time 😔
Has anyone else had this issue with the test?
