I’m getting worried

I suppose to be getting my period between 2 days ago to today I’m getting a little worried 2 days ago I starting getting light pink discharge everytime I wiped. Not enough to bleed through anything this lasted 2 days mind you this has NEVER happen to me before my period. Now I have had brown discharge for about half a day & now it’s starting to go away. I am Mild to no cramps I usually have terrible cramps & sore breast when my period is coming I have had none of this.
