could i still end up pregnant

my period was nov 27th to dec 2nd. i had sex on the 8th but got my period again and it’s very heavy 🥲 i got off the iud recently so hence why i have a period again probably after almost 10 days of it going away. just asking if i could still end up pregnant? and no this is not spotting. it’s absolutely my period happening again. so i don’t think i even ovulated form the 2nd until now. thanks.
