Had what I thought was my period but positive test

Ok so I had a stomach bug at the end of what was my period. Two weeks later I was still having brown discharge. Kinda weird. I was having some calmness which was weird cause I suffer from anxiety and smells were bothering me. My appetite had also changed. So I thought I highly doubt it but I took a test just to see. And it was positive!!! WTH!! Is this normal?
