Nancy Is 8 Months Pregnant

Nancy is 8 months pregnant. Her physician mentioned that the placental LH-like hormone levels had decreased. Should Nancy be concerned?

A) No; the secretion of an LH-like substance by the placenta is important in the first trimester, and Nancy's pregnancy is beyond the first trimester.
B) Yes; the secretion of an LH-like substance by the placenta throughout the pregnancy is necessary to maintain the pregnancy.
C) No; the placenta doesn't normally secrete an LH-like substance at any time during pregnancy.
D) Yes; a drop in the secretion of an LH-like substance this late in the pregnancy will disrupt normal embryonic development.
