bleeding is a fresh bleed. Brown discharge is usually old blood and as such could be due to a breakthrough bleed. Yet, I would suggest an assessment of the serum beta-hCG
titres along with a trans-vaginal sonogram to exclude/confirm pregnancy
. If pregnancy is excluded, you could be having some hormonal
imbalance perhaps due to weight disturbances or other causes which need to be diagnosed after a check up and further management planned. Hope this helps.
