Opk positive or negative?

Kristhel
Hi ladies! I'm a bit confused I have been using the clearblue ovulation test the past two cycles. I took one yesterday and I got a smiley face however the test to me doesnt look positive. I took another today and it looks positive however I took an answer ovulation test today too from the same pee sample and it seems negative. Help!? Am I ovulating yet? 
The top two are from today. 
Thank you!
