There are few factors that can cause leaking, here are the most common ones.
- The cup has not opened fully inside your vagina. Make sure that the cup is completely open by rotating it while pinching the bottom or wiggling it from side to side. You can feel with your finger that the cup bottom is completely round.
- The cup has been placed too high, so that it is next to the cervix and not below it (or partly around it). Blood flows from the cervix so if the cup is not below it the flow goes by. You can test where your cervix is located with your finger. Cervix feels a bit like the tip of your nose. If you can reach it, it is quite low and may come even lower during periods. Try to place the cup below the cervix or partially around it. You can read more about the cervix here.
- The air holes are blocked or dirty so the cup does not form a good seal. Make sure that all 4 air holes are open and clean every time you rinse the cup.
- You can try this little trick: When inserting the cup, push out with your pelvic muscles and place the cup inside so that the bottom stays outside. Rotate the cup so that it fills with air, you can feel with your finger that the bottom of the cup is completely round. This is vital because wrinkles or fold in the cup will make it leak. Then tense your pelvic muscles in and push the cup inside the vagina. Push a bit towards the spine because vagina is tilted. The correct place for the cup is below the cervix so you can also test with you finger where the cervix is located during periods.
- If the cup leaks after you have tried all these tips the culprit may be your pelvic muscles. If the pelvic muscles are a bit weak they cannot hold the cup tight against the vaginal wall. Then the cup usually leaks e.g. when you get up from a sitting position. Kegel exercises strengthen the pelvic muscles and prevent future problems like urinary leakage. These muscles also have a lot to do with sexual pleasure so a big bonus there to do some training!
