Menstrual Cycle: Understanding Symptoms, Causes, and How Medications Help

When we talk about the menstrual cycle, the monthly series of hormonal changes in a woman’s body that prepares it for pregnancy. Also known as period cycle, it’s not just about bleeding—it’s a complex system that affects your mood, energy, bladder, and even how your thyroid works. If you’ve ever felt sharp pain in your lower belly, sudden urges to pee during your period, or weird fatigue right before your flow starts, you’re not imagining it. These aren’t random glitches. They’re direct results of hormones like estrogen and progesterone rising and falling.

The hormonal changes, the fluctuation of estrogen and progesterone that drive the menstrual cycle and influence other body systems can mess with your thyroid, as seen in how ethinylestradiol, a synthetic estrogen used in birth control pills that can alter thyroid hormone levels and affect lab results shows up in studies. That’s why some people get weird thyroid test results during their cycle—even if nothing’s wrong with their thyroid. And then there’s the menstrual bladder pain, a common but often ignored symptom where the bladder becomes inflamed or irritated during menstruation. It’s not a UTI, but it feels like one. The same hormones that cause cramps can make your bladder lining swell, leading to urgency, burning, or even pain when you sit down. Ketorolac and other NSAIDs are often used to calm this inflammation, but they come with kidney risks if used too long. It’s a balancing act.
