Should i take a pregnancy test?

Me

Hey y’all I was spotting with pink discharge Sunday and Monday. Then yesterday and today it’s been brown. Not enough to wear a pad or have a tampon in though. I’m not due for my period until Monday. I’ve never had spotting before I was due for a period. I’m also unsure of exactly when I ovulated or if I have at all this cycle (pretty sure I did) as every OPK I’ve taken since last week has been negative. My last period was around the 5th of this month.
