Your expected period due date was around 23rd-26th February. Late period with pink bloody discharge is mostly suggestive of early sign of miscarriage
Therefore, you should undergo one home pregnancy
test with urine initially to check pregnancy status. One blood test
for beta HCG & TVS scan is required to confirm product of conception.
After that, you can consult with gynecologist for next line of investigation & management.
