Clomid OPK false positives????¿¿¿¿

Hi all! I just got done with taking my Clomid cycle days 5-9. Around cycle day 11 I noticed a change in my body and decided to test,I use the opk clear blue digitals,  I was at peak fertility. Then I decided to test on day 13 fertility was low. I thought that maybe I just OV early. But then I tested that night and had high fertility. Tested today and had high fertility. Did I get a false positive the first time? My husband and I are bd every 3 days in general but this is frustrating!
