Bleeding is never normal unless is implanation. Did your bleeding stopped after Duphaston? Ultrasound by vaginal or tummy scan by pte gynae? Sometimes when the embryo is too small or still in early pregnancy, it is harder to spot by tummy scan.
There is nothing much you can do now except to have more rest, do not carry heavy stuff and continue with Duphaston. Perhaps you can also request for jab for more support.
All the best.
