Is brown discharge normal

My period is due in two days. Sorry for the tmi, i noticed light brown discharge in my underwear today. Ive never noticed tht before a period before. I had unprotected sex 10 days ago and im not on the pill. Is it normal to have brown discharge so close to my period?

I always have brown discharge before I come on my period.

Usually brown discharge is from old blood not new so it's not usual on a normal period but can happen take a test of your unsure

I always get brown discharge 2 days before my period but I didn’t get any discharge on the month I fell pregnant . It’s was weird to me and still confused.
