My period is 8 days late, am i pregnant?

I had sex without condom 2 days before my predicted period. he didn't cum inside (at least i think so). now my period is 8 days late. i took a pharmacy test by the 5 day late and the result was negative, but i don't know if this is accurate, maybe it was too early. idk.

can i be pregnant?

p.s.: sorry if i wrote something wrong, i'm brazilian.
