Light brown/ tanish discharge

Macy

I recently got off the pill (have not had sex in 3 weeks and I got tested a few days ago and it was neg. for pregnancy) I just had light brownish discharge. Im supposed to have my period in 2 weeks but since I got off the pill I’m not sure if it will be sooner. I looked up brownish discharge and it says it could be a sign of pregnancy??? I’m a little worried pls give advice. Is it because I’m going to start my period soon or should I be worried about pregnancy?
