Answer
Tani,


She would not have conceived in March.



The research shows that the risk of placental deterioration and other such complications don't increase until after 42 weeks of pregnancy.  In some cases, I know of women who've gone as long as 44 weeks with no complications, but in general, if a woman hasn't gone into labor by 42 weeks, then an induction is medically necessary due to the increased risks of placental deterioration and stillbirth.



Best,
