1. Para 2 is concerned about risk of bleeding
after delivery as she had a PPH around 1000ml
of loss in her previous delivery 3 years back.
She asks whether any thing can be given to
reduce the risk of PPH this time.

2. Primigravida is awaiting for elective CS. She
has had several episodes of bleeding in the
antenatal period which were thought due to
placenta previa. However in the last USS at 36
weeks there was no evidence of placenta
previa.
