Signs progesterone is dropping before period & management tips

Progesterone is one of the essential reproductive hormones in females that helps regulate your menstrual cycle and prepare your uterine lining for pregnancy. It remains low through the first half of your cycle and naturally increases after ovulation for the lining to thicken. In a 28-day cycle, progesterone levels peak at around day 21, after which they drop rapidly to break the uterine lining (if pregnancy didn’t occur) and start your periods.

The main signs progesterone is dropping before period include:

• Spotting
• PMS
• Headaches
• Sleep issues

While low progesterone before period is a natural thing, if your body does not have enough of it after ovulation, this can cause a number of issues, including irregular menstrual cycle, infertility, and early miscarriage. This condition is known as luteal phase deficiency and requires personalized medical advice.

A female menstrual cycle, on average, lasts for 28 days, which count from the first day of a period until the day before the next period starts. The entire cycle consists of four stages: menstruation, follicular phase, ovulation, and luteal phase. Each of these stages plays an important role in female reproduction and performs a certain function. Their functions are controlled by women's reproductive hormones, estrogen and progesterone, the levels of which change through the cycle to stimulate the needed bodily processes. During these hormonal fluctuations, it's usual for women to feel different and notice certain discomforting symptoms. Still, it's absolutely natural to seek relief from these symptoms. And to find it, it's important to understand your cycle on a hormonal level. 

In this article, we’ll focus on the end of the luteal phase and discuss what the signs progesterone is dropping before period are and how you can ease your symptoms.

What Is the Luteal Phase?

The luteal phase begins around day 15 in a 28-day cycle. It starts after you ovulate and lasts until you get your period.

The 14 days of the luteal phase are commonly known as a two-week wait among women who are trying to conceive. This is due to the fact that it’s the luteal phase when implantation happens and pregnancy begins. Thus, the main function of this phase of the cycle is to prepare your body for implantation and help support early pregnancy.

What Is Progesterone and Its Role in the Luteal Phase?

Progesterone is the dominant hormone during the luteal phase. It’s produced from the corpus luteum, which appears from a ruptured follicle that has released the egg during ovulation. When ovulation is over, the levels of progesterone start rising. The primary function of this hormone is to make your uterine lining grow and thicken, so that it’s strong enough to anchor a fertilized egg.

How Do Progesterone Levels Change in the Luteal Phase?

Progesterone levels remain low (< 1.5 ng/ml) through the first half of the cycle. Then, they start rising rapidly from day 15 and reach their peak of about 25 ng/ml by day 21. Then, there is a small decrease between days 21-25, and a drastic drop from day 25 until the end of the cycle when your periods begin.

These are approximate natural fluctuations of progesterone during the luteal phase taken from laboratory tests. And, as you can see, low progesterone before period is a natural thing because by day 28 of the cycle (the day before periods) your progesterone levels should go back to < 1.5 ng/ml.

When Do You Have Low Progesterone Before Period?

Now, before we move on to the signs progesterone is dropping before period, let’s answer another important question – Why does progesterone drop closer to the end of the cycle?

This happens only if pregnancy doesn’t occur. In this case, your body receives a signal that there is no implantation and your progesterone drops, causing the uterine lining to break and shed, starting your period.

If pregnancy occurs, progesterone levels should continue growing through every trimester to support fetal growth and prepare you for labor and lactation. Due to this reason, monitoring progesterone levels and associated symptoms is widely used for early pregnancy monitoring, as well as detecting issues with fertility and the luteal phase.

Signs Progesterone Is Dropping Before Period

Now that you know how progesterone levels naturally change through your luteal phase, let’s explore the main symptoms of low progesterone before period:

Spotting

Since progesterone is directly linked with the shedding of the uterine lining, when its levels drop, the lining breaks. Typically, it should mark the start of your period. However, sometimes, when its levels drop too early, you may face progesterone spotting before your period begins. This light bleeding can take place a day or a few days before the start of menstruation.

Please note that it’s possible to mistake spotting before period low progesterone with implantation bleeding. Implantation bleeding can also take place close to the expected start of your period. However, in this case, menstruation won’t start.

Premenstrual Syndrome

Premenstrual syndrome or PMS is closely linked to progesterone levels. All the typical PMS symptoms, including irritability, anxiety, bloating, fatigue, mood swings, and breast tenderness, are signs of low progesterone. They appear closer to the start of your period and can vary in severity depending on how quickly and drastically progesterone drops.

Headaches

Hormonal headaches and migraines are also commonly associated with progesterone. The thing is that this hormone has a neuroprotective feature. In particular, it’s known to reduce inflammation and protect your brain from damage. As a result, when progesterone levels drop rapidly, some women can experience headaches.

Sleep Problems

Progesterone is responsible for another crucial function in the brain. It stimulates the production of GABA neurotransmitters that are responsible for reducing brain activity. In simple words, progesterone helps your brain relax and thus promotes sleep. Respectively, when this hormone drops, some women can find it harder to fall asleep or stay asleep.

Signs of Low Progesterone After Ovulation

While it’s natural to have low progesterone before period if you don’t attempt to get pregnant, it’s also possible that you face overall low progesterone levels, which is not natural and can cause certain issues. Low progesterone after ovulation is one of the common causes of luteal phase defect – a condition in which your uterine lining doesn't get thick enough to facilitate pregnancy.

Here are some of the signs of low progesterone after ovulation that you can watch out for:

Cycle Irregularities

Apart from preparing your body for pregnancy, progesterone also plays a big role in regulating your cycle. In a normal cycle, rising progesterone levels cause the uterine lining to thicken, and then dropping progesterone causes it to break for periods to begin. When your progesterone levels are generally low, this can lead to different cycle irregularities, including shorter or infrequent periods.

Fertility Issues

When your body doesn’t produce enough progesterone, this can cause your uterine lining not to thicken enough to anchor an egg. As a result, implantation cannot happen even after fertilization. Due to this reason, women with low progesterone often find it harder to conceive.

Early Miscarriage

When implantation happens, your body continues producing progesterone. This is essential for ensuring that the embryo gets all the necessary nutrients and develops properly. When your progesterone levels are insufficient, this can potentially result in an early miscarriage.

Effective Management Options for Low Progesterone

Although PMS symptoms, headaches, and other symptoms of dropping progesterone can be rather discomforting, they are natural. Luckily, this doesn’t mean that you can’t do anything about it.

Most specialists recommend the following tricks to address low progesterone before period:

• Proper diet with a focus on foods with vitamin B6, zinc, and magnesium
• Low-impact exercise
• Stress-management techniques
• Proper sleep
• Sufficient hydration

If you are also experiencing progesterone spotting, you can address the issue with the help of natural remedies, such as seed cycling.

Management gets a bit more complicated if your progesterone levels are generally low during your luteal phase. In this case, it might be a sign of a luteal phase deficiency, which requires a consultation with a healthcare provider. See your doctor to confirm low progesterone and diagnose any underlying issues. Based on the results, a specialist can prescribe progesterone supplementation, hormone-stimulating medications, or special treatments for underlying health conditions.
