At this stage there is nothing you can do about the bleeding - if you are pregnant, you are in the very early stages and spotting can occur. Spotting can happen in healthy pregnancies but it could also indicate a potential early miscarriage. There is no knowing at this time. Unfortunately there is nothing that can be done at this point.
Brown spotting is usually old blood which is a good sign - the body is getting rid of old discharge, perhaps from your last period. Give yourself another week or so to see what happens.
