ovulation tests...

So, we have been TTC baby no 3 for 5 months now.  I started using the clear blue advanced ovulation sticks last month and now this month ... I started testing yesterday on day 6.  Today is day 7 and I got the flashing smiley face... I feel like it's too early to see that face.  Thinking maybe either something wrong w the stick or some sort of hormonal imbalance?  Anyone have any insights???  Really hoping this is my month!!! Thanks!!!
