Ovulating twice? False positive? Clear blue digital!

Hi all
From my understanding you can't ovulate twice in one month - it's possible to release two or more eggs but not actually ovulate twice? 
Anyway I've started tracking my ovulation and I'm using clear blue ovulation test
I took the test and got low or no ovulation 
1.5 days later I got a solid smiley face meaning peak ovulation
That stays for 48hrs. 
48hrs later I got blank face / low ovulation 
Then flashing smile - high ovulation 24 hours after that
Now I'm back to solid smiley face! 
What does that mean? 
Could it be a false positive? Which one is more likely to be correct. I've had cm for both and cramps. Pregnant?
I'm so confused! 
Help!
