Quick answer
To insert a Flex Disc, pinch the sides together to form a narrow oval, aim the disc toward your lower back at a 45-degree angle, and push it in until the front rim tucks behind your pubic bone. Relax your pelvic floor, breathe out as you push, and never force it. If you feel resistance, change the angle slightly rather than pushing harder.
Why angle matters more than force
The vaginal canal curves toward the lower back, not straight up. Many first-time users push vertically and hit the vaginal wall, which causes discomfort and failed insertion. Tilting the disc so the far rim points toward your tailbone lets it slide past the pubic bone and settle into the vaginal fornix—the deeper space where a disc is designed to sit. If you feel a sharp pinch, stop and re-angle rather than pushing through it.
Relaxation and breathing techniques
Tensing your pelvic floor narrows the canal and makes insertion harder. Take a slow breath in, then exhale fully as you push the disc in. Some people find it easier to insert while sitting on the toilet with knees apart, or standing with one foot on the bathtub edge. Try both positions—most people have a clear preference after two or three attempts.
How to know it's in the right place
After insertion, sweep your finger around the rim to confirm the front edge is tucked behind the pubic bone. You should not feel the disc when you stand, cough, or walk. If you feel pressure or the disc slips down, it is not fully seated. A correctly placed disc sits horizontally, with the front rim higher than the back rim.
Step-by-step insertion checklist
- Wash your hands: Use mild soap and water for at least 20 seconds, then dry completely. This prevents introducing bacteria. Checkpoint: hands are clean and dry.
- Find a comfortable position: Sit on the toilet with knees apart, squat, or stand with one foot elevated. Choose the position where you feel most relaxed. Common mistake: trying to insert while tense or rushed.
- Fold the disc into an oval: Pinch the sides of the disc together so the rim forms a narrow oval. The patented notch on the Flex Reusable Disc gives you a natural grip point. Checkpoint: the disc is narrow enough to insert without force.
- Aim toward your lower back: Point the folded disc at a 45-degree angle toward your tailbone, not straight up. This follows the natural curve of the vaginal canal. Common mistake: pushing vertically, which hits the vaginal wall.
- Push and tuck the front rim: Slide the disc in until you feel the front rim pass behind your pubic bone. Use one finger to tuck it up and back. Checkpoint: the front rim is securely behind the pubic bone.
- Check the seal: Sweep your finger around the rim to confirm it is fully open and covering the cervix. You should not feel the disc when you stand or cough. If you feel pressure, remove and reinsert with a slightly different angle.
Product facts that affect insertion
- Flex Reusable Disc: Flex Reusable Disc is made from 100% medical-grade silicone and has a patented notch that makes folding and insertion easier. The notch gives you a defined grip point, so you can fold the disc into a narrower shape without it slipping out of your fingers during insertion.
- Flex Disc: Flex Disc is a disposable menstrual disc that holds the equivalent of 5+ super tampons and provides up to 12 hours of leak protection. Because it holds more than a super tampon, you can insert it once and wear it for up to 12 hours—useful for overnight or long days when you cannot change it frequently.
