when did I ovulate??

nikki • 22

so I usually get my periods on the 14 each month but last month I got my period on September 8th which is really early for me and I have regular periods..but it lasted as long as it usually does, 7 days, so my question is does anyone know if this affected my ovulation time or date for that month or when I could have ovulated since this period was so early..? or does ovulation usually happen on the same days every month whether periods are early or not? I'm kinda confused 😯🤔
