D&C question

Kandis

I had a D&C new years <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> and had a normal cycle afterwards, this month I've had light spotting only on toilet paper and mild cramps, its not time for aunt flow to start and have never had this before. Is it something yo be concerned about. It was a light pink on Tues and today its a light brown but very very light
