advice anyone ??

I had protected sex on Jan 3rd but the condom broke and he said he pulled out so i left it alone so two weeks passed by and i was bleeding i thought it was my period so i put on a pad it filled up . Then later that night it was light and stayed from the next two days (it lasted 3 days) . I searched it up on the internet and it said im experiencing implantation bleeding . It came a week early and my period has NEVER be 3 days or come early . So I don’t know if i should count it as a period or not ? I’ve been feeling extra tired and hungry lately . My expected period was supposed to get 2 days ago so I don’t know if i should take a pregnancy test . Can you comment and give me some kind of advice about what i should do . 😊
