Could I have ovulated early?

Hi everyone so my period came on time like glow said it would on 6/30 but only stayed 3 and a half days then nothing on the 4th then some very light spotting on the 5th so my question is since my period ended early is it possible I ovulated right after cause last month glow said my peak was the 16th and it was correct but this month says the 9th I have not reached my peak in fact my tests are not even getting darker and they should be by now what do you all think?
