Pains? Implantation? Ovulation? Confused!

Kayz
Hi all
According to Glow i was ovulating last Thurs to Sun.  I am due AF around 12-14th.  I baby danced while ovulating, today i've had some dull period like pains, more noticebale than ovulation pains and i tested to see if maybe glow was wrong and i'm not ovulating.. Could this be implantation pains after jusr 6 days?
