No one responds in other groups! 12 days bleeding and mystery

LJ

I had an MC in September. I have been bleeding for 12 days. My period (or so I thought) was 2 days late and pregnancy tests were negative.

On day 10 of bleeding a positive test which doctors confirmed (false negative, ugh) and now I await my 2nd blood draw to see if levels are rising or falling.

They don't know if I already miscarried or if I will. Blood is no longer brown, but watery and bright, needing 5 Pantiliners a day.

I don't know what to do. Return to work? Wait for disaster?

Does anyone have a similar story or advise?
