hi I'm new to all this I did a cheap pregnancy test on Thursday and came up positive. Saturday night I had a little bit of brown discharge when I went to the toilet. su day morning there was more, late afternoon enough to use a pad evening not a lot only when I go to the toilet. I did a cheap test su day morning and it was a faint positive. I've just done a clear blue digital and it said not pregnant. could this be a miscarriage happening really fast. please help
