Hey i experienced that same brown discharge, but later to find out i was pregnant. Call your doc and make an appt.
I'm sorry about ur miscarriage. sometimes ur body needs some time to go back to normal after a miscarriage. brown blood is usually old blood left out from a previous cycle and isnt always a sign that some thing is wrong. just to rule out pregnancy u always need to take a test once ur period is late or lighter cuz this also happens when ur pregnant.
Im curious..did you hav a miscarriage as well? i had a mc in june and now im having pregnancy symptoms again and in mid aug i had sum brown spotting 1day & the nxt sum bleed but nothing since very bad cramping blood test did show pregnancy hormones however my doc insists its leftover hormones from the miscarriage..
