Confused 😩

September 10 i thought i started my period , because i started bleeding . But as the hours went by my bleeding went from brown to light pink . Last day of my period thats when i had red spotting . During my period i was working and all of a sudden started feeling light headed . Now that my period is over Ive been getting light brown gooey cm . Ive been told that its because im getting my period . But i already had it 🤔 could i be pregnant? Btw i had unprotected sex two weeks before my period and my bf didn't pull out .
