Help....

So my period was due Friday, Wednesday morning I woke up and was bleeding. It was light but it was there. So I figure early period okay no big deal. Thursday morning it's gone, a little pink when I wipe in the morning and then light brown during the day. Friday nothing so I take a pregnancy test and it's very light but positive. Now being as impatient as I am I try 2 more durning the day both negative. But I figure it's just becuause it's the wrong time. So I try again with FMU today and nothing negative....am I crazy? Did it give me a false negative or is there still hope?
