Welcome to HCM,
A few drops of brown bleeding can be due to implantation
. You have neither mentioned date of your last menstrual period, nor expected date of due period. Implantation bleeding normally occurs, just before (2 to 7 days prior) the expected date of period. Bleeding during period is of red colour, heavy (containing lot of clots in it), which generally lasts for 3 days with associated symptoms, while bleeding due to implantation is pinkish/brownish in colour, very light (scanty/spotting), which does not last for 3 days, but in some women, intermittent spotting may occur for 1 to 2 days. To exclude pregnancy
, please get pregnancy test done.
Wishing you good health,
