Positive test but blood when wipe....

Butterfly

Hi ladies,

I was due on AF yesterday and no sign. Leading up to and yesterday i did tests which all showed postives. However when i have just been toilet there was brownish blood when i wiped. I had a miscarriage in September at 5 weeks as hcg wasnt rising. Do i now presume that im not pregnant? Feel really deflated. Any advice would be greatly appreciated. Thank you
