Dark Days Help Please

Sunettee • Suni Sharpe

So my period is suppose to start on the 15th of Oct however I've been seeing a dark discharge since last week Friday. Today the color was deep red and sticky not really a flow. Guess I'm spotting but how long should it last? What color should the discharge be? I also have these weird cravings, no I'm not pregnant just worried. What should I do??
