Over the course of your life, it\u2019s likely you\u2019ve blamed a lot of women\u2019s health issues on your hormones. If you\u2019re irritable the week before your menstrual cycle starts, you assume it\u2019s premenstrual syndrome (PMS). If you\u2019re having trouble getting pregnant, it could be a hormonal issue. Or if you\u2019re dealing with night sweats and other symptoms of menopause, you may chalk it up to a changing levels of progesterone and estrogen.\u00a0<\/span><\/p>\n

However, you might not realize that you\u2019re not producing enough progesterone unless you\u2019re in tune with these low progesterone symptoms and indicators.\u00a0<\/span><\/p>\n

What is progesterone?<\/span><\/h2>\n

Progesterone<\/span><\/a> is a sex hormone produced by the ovaries <\/span>after ovulation occurs<\/span><\/a>. More specifically, it\u2019s the corpus luteum that produces this hormone as a natural part of the menstrual cycle. The corpus luteum is the cyst that forms every month inside the ovaries right after an egg leaves the ovary. It releases progesterone to help make the uterus ready for pregnancy by stimulating the endometrium (the lining of the uterus) to secrete proteins that make the uterus more hospitable for nourishing a fetus.\u00a0<\/span><\/p>\n

If you don\u2019t become pregnant<\/span><\/a>, the corpus luteum breaks down, your progesterone levels dip, and menstruation eventually starts. However, if you do become pregnant, the placenta will eventually also produce progesterone to support the corpus luteum\u2014and the growing fetus. This prevents your body from producing more eggs, and it also helps get your breasts ready to produce milk. Progesterone also affects your mood and helps to regulate your blood pressure, <\/span>according to the Cleveland Clinic<\/span><\/a>.\u00a0<\/span><\/p>\n

How is progesterone tested?<\/span><\/h2>\n

If you have some infertility concerns\u2013maybe you\u2019re having trouble getting pregnant\u2013your healthcare provider might suggest getting your hormone levels, including your progesterone levels and your estrogen levels, tested. The best time to sample serum progesterone is during the <\/span>mid-luteal phase, 18 to 24 days after the onset of menses or seven days before the next menses are expected<\/span><\/p>\n

Luckily, it won\u2019t require anything too invasive. It just involves some bloodwork. You don\u2019t even need to do anything in advance to prepare. You\u2019ll just have to roll your sleeve up to give a blood sample, which will be taken to the lab and analyzed. This blood test is known as a serum progesterone test.\u00a0<\/span><\/p>\n

However, a single serum measurement may not provide all the information that\u2019s necessary for a diagnosis, according to <\/span>Heather Huddleston, MD<\/span><\/a>, director of the PCOS clinic at UCSF and a medical advisor for Allara. Your progesterone levels may vary, depending on the time of day and the timing of your menstrual cycle. If you have an abnormal result, do not panic! You may need to have repeat testing 2 to 3 days later.<\/span><\/p>\n

Your provider may want to discuss symptoms and the effect that they may be having on you.<\/span><\/p>\n

It might make more sense to see if your symptoms last for several months. \u201cOne month could just be an outlier,\u201d says <\/span>Suzie Welsh Devine, MSN, RN<\/span><\/a>, a women\u2019s health nurse and founder of <\/span>Binto<\/span><\/a>.<\/span><\/p>\n

What are normal progesterone levels?<\/span><\/h2>\n

A normal progesterone level will vary, depending on where you are in your menstrual cycle or your pregnancy. Typically, your levels will be low at the beginning of your menstrual cycle, and then they\u2019ll rise when your ovaries release an egg.\u00a0<\/span><\/p>\n

Different levels may constitute normal for different women. If you don\u2019t have symptoms, you may not need (or want) progesterone replacement even if your levels are low. \u201cSome physicians will recommend replacement to avoid miscarriage, premature delivery of a pregnancy, or problems with the uterine lining which could eventually lead to uterine cancer,\u201d says <\/span>Greg Marchand, MD<\/span><\/a>, OB-GYN and gynecological surgeon in Mesa, Arizona.\u00a0<\/span><\/p>\n

The following levels are considered a normal range for women during a typical cycle and during pregnancy.<\/span><\/p>\n\n\n\n\n\n\n\n

What do low progesterone levels mean?<\/span><\/h2>\n

It means that your progesterone levels are below the typical range (less than 2 ng\/ml), which may cause you to have certain symptoms. It\u2019s hard to say whether it\u2019s common. \u201cIt is difficult to say for sure,\u201d Dr. Huddleston says. \u201cOne issue is that it\u2019s actually hard to accurately measure progesterone. Progesterone is pulsatile and can vary across different times in the day. Thus, it is difficult to make a diagnosis of low progesterone on the basis of a serum measurement.\u201d\u00a0<\/span><\/p>\n
