If your period shows up too soon after ovulation, it could be quietly sabotaging your pregnancy plans. And today we'll uncover why. Welcome back. Today we are digging deeper into reasons why you may not be getting pregnant. Today. We're diving into the luteal phase. That's the second half of your cycle, why it matters for conception and what it means if it's too short. I worked with a woman who had been trying for over a year to get pregnant. She was tracking her ovulation every month. She was hopeful only to see her period would arrive just eight or nine days after ovulation. She told me it always does this. She didn't know that her timing was the issue. This is called a short luteal phase, and it wasn't giving her body a chance It needed to support implantation. Her story isn't unique, and if you've ever noticed spotting or an early period after ovulation, this may sound familiar. I'm gonna break down the problem in a way that blends eastern and western knowledge. Let's start with what is the luteal phase. This is the time between ovulation and your next period. It should ideally be 12 to 14 days after ovulation. You might be asking what happens if it's too short? Well, the embryo may not have time to implant before the lining starts to shed. It may lead to spotting PMS or early bleeding. I hear from my patients they thought ovulation was enough. No one ever told me about the luteal phase and why it's so important. So let's dig into some root causes. Such as low progesterone stress, thyroid imbalance, inflammation, and blood sugar swings. From the Eastern perspective, we're gonna focus on the kidney, young, deficiency, blood deficiency, and the q not holding. We're gonna take a peek at these root causes and I'll provide some helpful tips. Number one, low progesterone production. Progesterone stabilizes the uterine lining, making it sticky for implantation. If levels drop too soon, the lining sheds early, which means you either have an early period or spotting. So let's take a look at what our hormones are actually doing. Estrogen is the foundation and framework in the first half of the cycle, which is called the follicular phase. Estrogen stimulates the uterine lining, which is our endometrium to grow and thicken. Think of it as laying down the initial groundwork and scaffolding for a future home. The implantation site, progesterone is the builder and stabilizer. After ovulation, progesterone takes over In the luteal phase, it makes the lining more glandular, nutrient rich, and receptive. Essentially, it's adding the plush layers, the soft carpets, the cozy environment for an embryo to implant. Every month we're recreating this luxurious home for the embryo to implant and grow. From the Eastern perspective, estrogen's action is nourishing blood, providing yin to build tissue. So progesterone's action is gonna be the kidney yang and chi, securing that pregnancy, warming, and holding the lining in place. This could be happening because you have poor ovulation. Quality stress could be suppressing your ovulation, or you could have nutrient deficiencies such as B six, magnesium or zinc. Some helpful tips would be supporting ovulation quality with blood sugar balance. That means no skipping meals. Make sure you add protein and fat for your snacks. Eat foods that are rich in B six, such as bananas, chickpeas, and salmon. And this naturally supports progesterone from the eastern perspective. You'll wanna strengthen that kidney yang. So we would use, special herbal formulas, warming soups, cooked root vegetables, and even try maybe a ginger tea. Reason number two, thyroid imbalance. Thyroid hormones regulate metabolism and fertility. Even mild hypothyroidism can shorten the luteal phase. Some clues to look for would be fatigue, tiredness, cold intolerance, constipation, and hair loss. Some helpful tips would be to request a thyroid lab and you want one that looks beyond just TSH. You wanna include free T three, free T four, and both of the thyroid antibodies. Make sure that we're feeding our thyroid with nutrients such as selenium. Remember just two Brazil nuts a day. Iodine such as seaweed, but make sure that you're not doing a huge iodine supplement because it could be overwhelming taxing to your thyroid and good sources of iron would be lentils and grass-fed meats. From the eastern perspective, we focus on the kidney yang and spleen cheese, so we wanna often strengthen them for metabolism and more. reason number three, chronic stress and cortisol dysregulation. High stress can steal from progesterone. This leads to all luteal deficiency. Stress also signals the body that it's not a safe time for pregnancy. So let me explain. Pregnenolone is the mother hormone, the precursor that can be converted into either progesterone, which is then converted to estrogen, testosterone, or some other hormones. Or it can be converted to cortisol, which is a stress hormone through different pathways. Under chronic stress, your body prioritizes survival over reproduction, so more pregnenolone gets shunted towards cortisol projection instead of progesterone. The result is lower progesterone levels. Creating a weaker luteal phase and a harder time maintaining implantation in early pregnancy. Your body uses its core reserves for fight or flight instead of reproduction, leaving less available to nourish and hold a pregnancy. Some helpful tips would be to reduce pregnenolone, steel and support cortisol regulation. For stress regulation, you need to prioritize daily rituals to calm your HPA axis. Things such as yoga, meditation, nature walks and journaling. Blood sugar balance is very important. It prevents additional cortisol spikes, so eat regularly and make sure you have adequate protein and fats. We wanna support our nutrients. Such as vitamin C, magnesium and B vitamins, especially B five.'cause these are co-factors in adrenal and progesterone pathways. Make sure that you're getting restorative sleep. Deep sleep restores our adrenals, so we wanna aim for seven to eight hours and try to get an optimal environment and a nice, cool, dark bedroom. Reason number four. Inflammation and gut health inflammation increases prostaglandins, which can destabilize the uterine lining and shorten luteal phases. So poor gut health disrupts estrogen and progesterone metabolism. Some helpful things would be to add anti-inflammatory foods, omega threes, like wild salmon chia seed, add some anti-inflammatory turmeric and green leafy veggies. Make sure you limit processed sugar and alcohol because they're very high and inflammatory markers, and really affect the gut and the liver. From the eastern perspective, we wanna move blood and qi with circulatory herbs such as donga and swong, which would be most likely in your herbal formulas during that part of your cycle. And we wanna gently support digestion with warming spices. Reason number five, blood sugar imbalance. We've mentioned this a couple times. Blood sugar swings can cause insulin resistance that can disrupt ovulation leading to low progesterone, which then leads to a shorter luteal phase. Some helpful tips would be pairing carbs with protein and fat, such as apples and almond butter. Avoid long gaps without eating, so make sure you keep some snacks in your bag. And from the eastern perspective, we wanna focus on our spleen cheese. We want to eat warm cooked meals rather than cold, raw salads and foods. And I know people hate it, but try to avoid ice in your drinks. Reason number six, nutrient deficiencies. First of all, our soil is so deeply depleted. Almost everyone needs support, vitamins and minerals, fuel, egg quality, progesterone production, and endometrial stability. Some of the key nutrients are gonna be vitamin D, magnesium, omega threes, B vitamins, and iron. Some helpful tips would be to focus on a whole food nutrient dense diet. Again, we wanna add grass fed meat, leafy greens, seeds, nuts, and colorful veggies from the eastern side of things, think of blood deficiency signs, which would be a pale tong fatigue or tiredness, a light or scanty period. You can nourish this with bone broth, goji berries, and dark leafy greens. We've talked about six great ways to support our luteal face. So let's recap real quick. Focus on progesterone production. Get to know your thyroid numbers and function. Reduce and regulate your stress, heal your gut. Keep your blood sugar balanced and feed your body where it's deficient. It a short luteal phase is not a life sentence. You can change it. The woman I was speaking about in the beginning, after a few months of balancing her hormones, supporting her luteal phase with herbs, nutrition, and lifestyle shifts, her cycles lengthen. And she finally saw two pink lines on her pregnancy test. So when we support our body's natural rhythm, fertility often flourishes. Some actionable insights that aren't overwhelming for you today would be. Track your cycle length and luteal phase simple BBT charting. You're gonna take your temperature first thing in the morning before you get up to use the restroom or talk to your spouse. This will tell you so much more than many of those expensive gadgets and tests. Focus on supporting progesterone, healthy fats, stress reduction and blood sugar balancing. Make sure you're incorporating restorative lifestyle practices. Better sleep, lower your stress, eat warming foods in the luteal face.
