How to Use a Period Bikini for Heavy Flow Days

Quick answer

Wear a period bikini on heavy flow days by pairing it with a backup like a menstrual cup or disc, timing your swim for lighter flow, and rinsing the suit in cold water after use.

Diagnosis: How to use a period bikini on heavy flow days

• Symptom: You notice leaks or feel anxious about swimming on your heaviest days.
• Likely cause: Heavy flow can exceed the absorbency of a period bikini alone, especially during the first 24-48 hours of your period.
• Corrective action: Wear a menstrual cup or disc as backup. Insert it before putting on the bikini. Swim for 1-2 hours, then rinse the bikini in cold water. Change into a dry suit after swimming. If you still feel unsure, consider skipping the swim on your heaviest day or using a dark-colored bikini.
• Stop or choose another option: If you experience leaking through the bikini and backup, stop swimming and change into a pad or tampon. Consider a different period product like period swim bottoms with higher absorbency.
