Brown spotting???? Please help!!

Jessica

So yesterday I was feeling bad. I couldn’t get rid of a headache. So I took some medicine and went to bed. Woke up this morning to a dull headache and brown spotting??? Has anyone had brown spotting before. I looked it up and it said something about implantation bleeding but my period was just a week ago. I mean it was a short light period but still. Need help. Should I see a doctor??
