Sometimes, the failure of the corpus luteum to adequately support the pregnancy with progesterone can result in an early pregnancy loss.
Progesterone inhibits immune responses, decreases prostaglandins, and prevents the onset of uterine contractions.

For most women, ovulation takes place about 11 – 21 days from the first day of the last menstrual period.
Doctors will often use the quantitative test if they are closely monitoring the development of a pregnancy.
