could i still be pregnant? PLEASE HELP!

ol

hi guys, so i thought i got my period last week (on the 3rd). i bled heavily/a normal period amount for a couple days, then spotted very light brown for 4 days after my period was supposed to end which is really unusual for me. my breasts have also been hurting which is unusual, they always stop hurting when my period starts.

i took a test today because i was nauseous and it said positive.

my question is, could it be possible that my "period" last week was actually an early miscarriage and there are enough hormones in my body to still test positive?

is it possible to have period-like bleeding for a couple days and still be pregnant?

thank you so much for your help. if i am pregnant it would only be 5ish weeks
