She may have rehearsed the sentence before saying it. She may also take it back the moment you look worried. Your first response can decide whether the conversation grows clearer or disappears.
Start with what she knows
She may not know the cause. She may only know that she is missing school, waking at night, bleeding through protection quickly, or giving up things she normally does. That is enough information to begin listening.
Say: “Thank you for telling me. What has this been getting in the way of?” This keeps the focus on her life instead of asking her to judge whether the pain is serious enough.
Do not use your period as the measuring stick
A mother, sister, or friend may have had difficult periods too. Shared experience can create empathy, but it can also make disruption seem inevitable. “Mine were the same” should not close the conversation.
Try: “I had difficult periods too, but I want to understand what yours are costing you.” Her experience does not become ordinary because someone else learned to live around a similar one.
Ask what she wants from you today
She may want information, help arranging care, company, privacy, or nothing beyond being heard. Do not assume disclosure is permission to call a doctor, tell another family member, or take over the next step.
Offer a small choice: “Would you like me to listen, help you write this down, or help you think about who to speak to?” Agency matters especially when her body already feels difficult to control.
Know when to help her seek urgent care
Severe or rapidly worsening pelvic pain, fainting, dizziness, heavy bleeding, or pelvic pain when pregnancy is possible can require urgent medical help. Use the urgent care services available where you live.
You do not need to identify the cause. Help her describe what is happening now, bring any medicines she uses, and stay with the immediate question: what care does she need today?
