Involving unprotected sex and presence of brownish discharge one week before period due date is mostly suggestive of early implantation
bleeding. All above clinical presentation is also seen in early week of pregnancy
Here, you should undergo one home pregnancy test with urine initially around your due date or immediately after missed period to check pregnancy status. One blood test
for beta HCG
& TVS scan (around 4-5 weeks) is required to confirm product of conception.
After that, you can consult with gynecologist for next line of management for this condition. In exclusion of pregnancy, other relevant investigations are to be carried out.
