Using a table of random numbers, participants will be divided into 2 equal groups. Group A (57 patients) in which warfarin will be started day 2 after caesarean delivery (i.e. 24 hours postoperative), and group B (57 patients) in which warfarin will be started day 5 after caesarean delivery, then maternal complications are compared among these 2 groups.
