A pregnant woman (in her first trimester) is concerned that she has been exposed to a chemical that blocks estrogen and progesterone receptors so that the body does not recognize these hormones. The reason she should be worried about this is:
A) that FSH and LH may cause the release of another egg. B) that menstruation may occur, thus causing the embryo to be lost. C) that early labor may be triggered later in pregnancy. D) that relaxin may be inhibited.
