Why Does My Period Hurt? (Understanding Period Pain)

Why does my period hurt? If you’ve ever curled up with a heating pad wondering why cramps can feel so unbearable, you’re not alone. Nearly every woman experiences menstrual pain at some point in her life, but when cramps are severe, they can disrupt daily life and leave you feeling frustrated and drained.

At SheCycles, we believe you deserve both knowledge and comfort—so let’s break down why period pain happens, when it’s normal, and how you can find relief.

What Causes Period Pain?

The main culprit is prostaglandins—natural chemicals in your body that trigger uterine contractions to shed the lining each month. The higher the prostaglandins, the more intense the cramps.

These contractions can cut off oxygen to the uterine tissue briefly, leading to that aching or stabbing pain you feel. It’s the body’s way of pushing through the cycle, but it doesn’t make the discomfort any easier.

Primary vs. Secondary Dysmenorrhea

Primary Dysmenorrhea

This is the most common type of pain, caused directly by prostaglandins. It usually peaks on Day 1 of your period, then fades as hormone levels drop. While uncomfortable, it isn’t linked to a medical condition.

Secondary Dysmenorrhea

This type of pain is caused by an underlying condition like endometriosis, fibroids, or pelvic inflammatory disease. The cramps often start earlier, last longer, and can feel more severe over time. If your pain is unbearable or worsening, it may be worth speaking with a doctor.

Why Is My Period Pain So Bad on Day 1?

Many women ask: Why do period cramps hurt so bad the first day? The answer again comes back to prostaglandins—they peak at the beginning of menstruation. That’s why cramps often hit hardest on the first day, then gradually ease.

When Is Period Pain Normal—and When to Talk to a Doctor

Period pain is common, but it shouldn’t leave you unable to move or missing days of life every month. If cramps are:

• Unbearable or worsening with age
• Unrelieved by self-care or medication
• Accompanied by other symptoms like nausea, heavy bleeding, or pain outside your period

…it may be time to see a doctor. Pain that controls your life isn’t “just part of being a woman.”

Relief Tips: How to Ease Period Pain

The good news? There are ways to manage period pain:

• Heat therapy → heating pads or warm baths relax muscles and boost blood flow.
• Gentle exercise → movement releases endorphins, your body’s natural painkillers.
• Hydration & nutrition → staying hydrated and eating anti-inflammatory foods (like ginger, leafy greens, and omega-3s) can ease symptoms.
• OTC options → NSAIDs like ibuprofen reduce prostaglandin production if taken early.
• Alternative care → yoga, magnesium supplements, and herbal teas may also bring relief.

Connecting to Your Body & Cycle: Emotional Self-Care

Pain doesn’t just affect your body—it can weigh heavily on your emotions, too. When cramps strike, it’s okay to rest, to say no, and to care for yourself first. Remember: your body is working hard, and responding with kindness, patience, and self-compassion is part of the process.
