concerns/question.

my boyfriend and had a miscarriage in march and started trying to gwr pregnant again. I am 2 days late for my period and it is usually like clock work. I did take a pregnancy test 2 days ago and it had a really faint positive line, but I could have been seeing things. When I went to the bathroom this morning I had a brown discharge and as the day goes on it has faded into a lite pink. I just keep praying that I am pregnant. Any advice on how to take this or anyone else had this happen. if so where did it lead?
