I have a family member who had told me she was pregnant, about 5-6 weeks on a thursday. On the Friday, she messages me to tell me she had been bleeding and believed she was having a mc. On the Tuesday, she said she had taken a pregnancy test yesterday and it had confirmed that she had miscarried by giving a negative result. I guess something just doesn't add up (there is more to the story). I would have thought it would take longer than 3 or 4 days for hcg to be out of your body to give a negative pregnancy test. Does anyone know roughly how long it takes to get a bfn after mc?
