Ovulating twice the same cycle?

Christina
Ok ladies, this one confuses me! I began testing with Clear Blue Digital OPK and these are my results so far...
Cycle day 7 - O
Cycle day 8 - 😀
Cycle day 9 - O
Cycle day 10 - 😀 
So I had an LH surge on CD 8 and again on CD 10. Is this possible? Or could something be wrong with the tests? Plus I ovulated so early so that's weird to. HELP! I called my doc but haven't gotten a call back yet.
