i'm 5 weeks now too and I also have a little brown. My doctor said the brown stuff is just the remaining "M" from last cycle so don't need to worry wor !! He said if it's not red blood coming out then it's fine. My last pregnancy had both red and brown too but turned out everything is fine and my daughter now is already 4 la !! no worries i guess.
i'm at 5wk. last night i had stomach
ache and some blood, not little, just
like day3-4 of m.
i went to QE and stayed for 1 night.
doctors can sure if it's miscarriage
'cos bb is too small to find. i can
only wait and see. i have 1-week
sick leave. i now don't bled a lot,
some blood only.
