Ive had brown spotting for 5 days now. Its not later in the afternoon and I've just taken a pregnancy test which came out positive. It's the first time I've had this brown spotting happen, but it feels like my period is coming. Or could be just me hoping it will. Could the pregnancy test by any chance be wrong?

Most likely the pregnancy test is right if you read it within the time constraints given on the directions.

Take another in the morning using first morning urine to be sure.
