Progesterone normal levels can vary depending on the specific phase of the menstrual cycle and whether a woman is pregnant. In the luteal phase of the menstrual cycle (after ovulation), Progesterone levels typically range between 5 and 20 nanograms per milliliter (ng/mL). During early pregnancy, Progesterone levels increase significantly and can reach levels above 10 ng/mL. However, it is important to note that Progesterone levels can vary between individuals, and the reference ranges may differ based on the specific laboratory or healthcare provider. Additionally, Progesterone levels can be influenced by various factors such as age, underlying medical conditions, medications, and hormonal imbalances. Therefore, the interpretation of Progesterone levels should be done by a healthcare professional in the context of the individual's overall clinical picture and specific circumstances. Consulting a healthcare professional can provide a more accurate understanding of what is considered a normal Progesterone level in a particular situation.
