In women of reproductive age, Progesterone levels vary throughout the menstrual cycle. Progesterone levels are typically highest during the luteal phase, which occurs after ovulation. During this phase, if pregnancy does not occur, Progesterone levels decline, triggering the shedding of the uterine lining and the start of a new menstrual cycle. In pregnant women, Progesterone levels continue to rise throughout pregnancy and are highest during the third trimester. It is important to note that Progesterone levels can vary between individuals and depend on factors such as age, overall health, and specific circumstances. A healthcare professional can provide more accurate information regarding Progesterone levels based on individual situations.
