Clear Blue ovulation test shows 2 separate LH surges

So I have been tracking my ovulation for the past 4 months. This month I decided to switch to clear blue since you get a smiley face or circle rather than trying to read other tests with lines. Also I wanted to switch it up to see if different brands tell me different O days. With the clear blue this month I saw my most fertile days fr day 10-14 (pretty typical of what I've seen fr the 2 line tests) with my peak fertility on day 13&14. So I tested day 15&16 to see that I got no LH surge-great just what I would assume to see since my O should be over this month. So I test again today because I like to have every piece of info on my body and I got another LH surge with a flashing smiley face. I've never had two surges show before using tests. Has anyone else had this problem?? I'm worried because I've read this could mean your body isn't ovulating so it makes several attempts throughout the month.. then I also read it could mean pregnancy but it's far too soon inmy cycle to test. Has anyone else used the clear blue digital tests and seen this? If so what came of it for you?
