Progesterone: What it does and how to check your levels
Progesterone is a key female hormone that helps regulate your cycle, supports early pregnancy, and affects mood and sleep. If your periods are irregular, you have spotting before your period, or you've had trouble conceiving, low progesterone might be one of the reasons. A single blood test taken about a week before your period ends (mid-luteal phase) tells most doctors what they need to know.
When doctors use progesterone
Clinicians prescribe progesterone for clear reasons. It's commonly used for luteal phase support in IVF or after timed ovulation to improve chances of implantation. Women with a history of early miscarriages sometimes get short-term progesterone in the first trimester. Progesterone also comes up in hormone therapy for menopausal symptoms, though routes and doses differ. Don’t assume that more is better—your doctor will pick the form and timing that fits your situation.
Forms matter: oral capsules (micronized progesterone), vaginal gels or suppositories, and topical creams. Vaginal delivery often gives higher local levels in the uterus with fewer sleepiness or systemic side effects than oral. Topical creams are common online but their absorption is variable; talk with a clinician before switching to a cream you buy without a prescription.
Practical tips to support healthy progesterone
Small lifestyle changes can help keep hormones balanced. Reduce chronic stress—high cortisol can suppress progesterone. Aim for steady blood sugar (regular meals, balanced carbs and protein) and avoid extreme dieting. Key nutrients linked to hormone balance include vitamin B6, magnesium, and zinc; a basic multivitamin or food-first approach is a sensible start. If you're preparing for IVF or trying to conceive, ask your clinic about supplements they recommend—myo-inositol is often suggested for ovulation quality in certain patients.
Watch out for side effects if you start prescribed progesterone: common ones are breast tenderness, bloating, mood swings, and sleepiness. If you feel severe mood shifts, unusual bleeding, or signs of an allergic reaction, get medical advice right away. Progesterone can interact with some medicines that change how your liver breaks down drugs—always tell your provider about everything you take, including over-the-counter herbs.
Testing and timing matter. A single mid-luteal progesterone test helps confirm ovulation. Repeated tests or saliva/urine home kits are sometimes used but interpret those results with care—lab blood tests remain the standard. If you’re on a treatment plan, your doctor may adjust dose or route based on symptoms and test results.
If you want practical next steps: track your cycle for a few months, note symptoms (spotting, premenstrual issues, mood changes), and bring that log to your clinician. Ask whether progesterone testing, short-term supplementation, or referral to a fertility clinic makes sense.

As a blogger, I recently came across the topic of progesterone, a hormone that plays a crucial role in our bodies. It turns out that progesterone is often referred to as the "miracle hormone" due to its numerous health benefits, such as regulating menstrual cycles, improving mood and sleep, and even supporting a healthy pregnancy. However, many of us might not be getting enough of this vital hormone through our diets. To boost progesterone levels, it's essential to consume foods rich in vitamin B6, magnesium, and zinc, such as lean meats, fish, whole grains, and leafy greens. So, let's make sure we're including these nutrient-packed foods in our meals to reap the amazing benefits of this miracle hormone!
