Can You Bleed Through a Menstrual Cup?

Short answer: Yes — it can happen, especially if your flow is heavy, but it’s usually not a sign that the cup isn’t working.

🔹 Common Reasons for Leaks

  1. Cup isn’t fully open

    • The cup must “pop” open inside the vagina to create a seal.

    • Run a finger around the base after insertion to make sure it’s open.

  2. Wrong size or shape

    • Small cups may overflow on heavy days.

    • Large cups may be uncomfortable or not seal properly if your vaginal canal is short.

  3. Not positioned correctly

    • The cup should sit low in the vaginal canal, just below the cervix.

  4. Overfilled

    • Even a correctly placed cup can overflow if your flow is very heavy.

🔹 How to Prevent Bleeding Through

  • Check that the cup is fully open and sealed after insertion.

  • Consider a larger size or higher-capacity cup for heavy flow days.

  • Empty more frequently on heavy days (every 4–6 hours if needed).

  • Use period underwear or a pad as backup while adjusting to your cup.

🌸 Bottom Line

Bleeding through a menstrual cup is common at first. With the right size, proper insertion, and correct emptying schedule, most people find cups leak-free and reliable.
