Ovulating twice?

Hi all!  New to this site and trying for a third.  Our second took 3 months of clomid after a year of TTC.  Now she's three and trying again.  
​This past week took an ovulating test and was + for 2 days.  Checking my cm daily and today started to notice a difference along with pangs from ovaries (same as last week).  Took another ovulation test and it's + again.  
​Anyone else have this??
