Menstrual discs are a comfortable, high-capacity alternative to traditional period products, fitting into the vaginal fornix to collect menstrual flow. Their design allows for mess-free intimacy and wear times up to twelve hours. Standard insertion methods can be difficult for users whose internal anatomy varies from the typical configuration. This article provides specialized guidance for using a menstrual disc successfully despite having a retroverted, or tilted, uterus, focusing on adjustments to placement and removal.
Understanding Uterine Position and Disc Placement
A retroverted uterus is a common anatomical variation where the organ tilts backward toward the spine and rectum, affecting 20 to 30 percent of people with uteruses. This orientation often influences the position of the cervix, which is the opening to the uterus and the point the disc must sit beneath.
When the uterus is tilted backward, the cervix usually positions itself closer to the posterior vaginal wall. A menstrual disc must be tucked securely behind the cervix and hook its front rim behind the pubic bone. With a retroverted anatomy, the cervix’s backward tilt reduces the space in the posterior fornix, making it challenging for the disc’s back rim to clear the cervix and sit beneath it.
The disc must cup the cervix to collect flow, requiring a modified angle of approach. While the pubic bone remains the front anchor point, the path to get the disc’s back rim past the cervix changes significantly. Understanding this altered internal geography explains why a simple straight-in push will likely fail to position the disc correctly.
Specific Insertion Techniques for a Retroverted Uterus
Achieving a correct fit requires an altered insertion angle that acknowledges the cervix’s backward tilt. Fold the disc into a figure-eight shape and aim it distinctly downward and backward, toward the tailbone or rectum. This downward initial angle directs the disc beneath the cervix, which is seated lower and further back than in a typically positioned anatomy.
Once partially inserted, use a “scooping” motion to guide the back rim to clear the cervix. Angle the disc down, then use a gentle upward sweep to ensure the rim passes under the cervix and settles into the vaginal fornix behind it. The goal is to feel the cervix resting inside the bowl of the disc, confirming the back rim is positioned correctly.
Changing your body position can temporarily adjust the pelvic tilt and make the cervix more accessible. Experimenting with different postures is recommended. These positions can slightly shift the angle of the vaginal canal, creating a clearer path for the disc to bypass the tilted cervix and settle into place.
Adjusting Body Position
You can try several positions to aid insertion:
- Squatting low.
- Raising one leg onto a toilet or tub edge.
- Lying on your back with your knees bent.
After the back of the disc is positioned behind the cervix, push the front rim up until it hooks securely behind the pubic bone. This tucking motion keeps the disc in place and prevents leaks. Ensure the disc is pushed high enough to engage the pubic bone, as insufficient tucking can cause the disc to come loose.
Troubleshooting Placement and Removal
After initial placement, check the seal to confirm the disc is fully tucked and covering the cervix. Run a clean finger around the rim, ensuring no portion of the cervix is exposed and the front rim is firmly tucked behind the pubic bone. If the disc has slipped or the cervix is not fully covered, remove and reinsert it, adjusting the backward angle.
Leaks usually indicate the disc has not fully cleared the cervix and is sitting in front of it. In this case, the disc diverts flow instead of collecting it, requiring a more deliberate downward and scooping insertion motion. Consistent, heavy leaking suggests the disc is not positioned correctly underneath the cervix, or that the degree of retroversion makes disc use difficult.
Removal can be challenging if the disc sits high or the pubic bone tuck is secure. To ease the process, gently bear down with your pelvic floor muscles, similar to a soft push during a bowel movement. This action helps slightly dislodge the front rim from the pubic bone, bringing the disc lower and making the removal rim easier to reach.
Squatting can also significantly shorten the vaginal canal, aiding in reaching the rim for removal. Once the rim is reached, hook a clean finger underneath it and pull the disc out horizontally, keeping it level to minimize spillage. If you consistently struggle with reach, selecting a disc model with a dedicated removal aid, like a loop or tab, can be beneficial.
