Without breastfeeding the first menstrual flow usually begins --- weeks after delivery?: (A) 2-4 weeks, (B) 4-6 weeks, (C) 6-8 weeks, (D) 8-10 weeks
Answer is C. This is variable and depends upon whether the woman is lactating. Nonlactating mothers have an early resumption of menses by about 6-8 weeks. In nursing mothers, approximately 70% are amenorrheic until 4-6 months (refer pgno:424 Sheila 2 nd edition)
