Period care — Do & Don’t
Simple reminders to help you stay comfortable and care for yourself during your period.
- Wash your hands before and after changing a period product.
- Change pads or tampons regularly and follow the product instructions.
- Rest when you need to, stay hydrated, and keep track of unusual symptoms.
- Don’t douche or use strongly scented products in or around the vagina.
- Don’t keep a period product on longer than recommended.
- Don’t ignore very heavy bleeding, fainting or dizziness, or severe or worsening pain.
These are general self-care tips, not a diagnosis. Seek medical care if symptoms are severe, unusual, or worrying.
