One day with a period

Hey ladies, so i definitely thought this month was going to be it. My boobs were sore for almost 2 weeks, i was super tired, i just thought it was going to be this month that i got pregnant. I tested 3 days before my period & a BFN... 2 days before my period, again BFN.

But then my “period” came.. it was only for a day, it was brownish-then became reddish.. the next day it was nothing. Today is day 2, day 2 is normally the WORSE, like gushing blood(sorry tmi) but there’s nothing.. i even slept without a tampon in.. and nothing. Me & my fiancé had sex... no blood at all! Should i retest? Has anyone had anything like this before?
