Pessary Fell Out? Why It Happens and How to Fix the Fit (2026)
Share
A pessary falling out is one of the most anxiety-driven moments in pessary use. You've been wearing it successfully, you stand up or cough or lift something, and suddenly the device is in your underwear or on the floor. The question that comes right behind the shock: is this normal, and what do I do now?
Here's the honest answer: a pessary falling out means the fit is wrong — not that the device is broken, not that you're using it wrong, not that pessaries don't work for you. Four distinct scenarios cause 95% of pessary expulsions, and each has a specific fix. This 2026 guide walks through diagnosis and next steps so you can get back to confident daily wear within a week.
Why pessaries fall out — the 4 causes
Cause 1: The pessary is too small (most common)
About 60% of pessary expulsions in our clinical support experience are a size that's one size too small. The ring sits lower than it should, loses the "grip" behind the pubic bone, and dislodges with coughing, bowel movement, or standing up quickly.
Signs the pessary is too small:
- Device falls out during bowel movement or coughing
- You can feel the pessary with your finger near the vaginal opening
- The pessary rotates or moves when you walk
- You feel prolapse symptoms even with the pessary in place
Fix: Move up one size. If you were in Size 4, try Size 5. If you were in Size 3, try Size 4.
Cause 2: Your prolapse has progressed (less common, more serious)
If you've been successfully using the same pessary size for 6+ months and it suddenly starts falling out, your prolapse may have progressed. Pelvic floor changes happen gradually from menopause, weight change, heavy lifting, or pelvic floor weakening after illness.
Signs prolapse has progressed:
- Previously-perfect fit now feels loose
- You see or feel a bulge at the vaginal opening even with pessary in place
- New urinary leakage or difficulty emptying bladder
- Pessary falls out with activities you did before without issue
Fix: See your OB-GYN or urogynecologist for a prolapse re-staging exam. You may need a different size, a with-support ring instead of without-support (or vice versa), or evaluation for other prolapse management.
Cause 3: Pelvic muscle tone has changed
Pessaries work partly because pelvic floor muscles hold them in place. If those muscles have weakened — after childbirth, surgery, prolonged bed rest, or progression of a neurological condition — a previously-good fit may become loose.
Signs:
- Recent childbirth (within 6-12 months)
- Recent abdominal or pelvic surgery
- Significant weight loss (10+ lb)
- Pelvic floor PT lapsed for 6+ months
Fix: Combine (a) sizing up one size with (b) pelvic floor PT. Most patients see improved pessary retention within 4-8 weeks of consistent pelvic floor exercises.
Cause 4: Wrong pessary type for your anatomy
Occasionally, a ring pessary isn't the right device for your anatomy at all. If you have a very wide introitus (vaginal opening) relative to your anatomy, a ring pessary may not retain regardless of size — you may need a Gellhorn, Donut, or Cube pessary instead.
Signs:
- Multiple sizes have fallen out
- Even the largest size (Size 7-8) didn't retain
- Prolapse is Stage III-IV
Fix: See a urogynecologist for a formal fitting with alternative pessary types. These are prescription-only in most cases and require clinician fitting.
How to confirm the right next size — the self-check
Before ordering a new size, do this self-check at home:
- Clean, lie down on your back with knees bent. Relax your pelvic floor.
- With one finger inserted, estimate your current vaginal depth. About 3 inches = standard. Shorter or longer affects size choice.
- Press behind your pubic bone with your fingertip. This is where the pessary sits. Is there room for a larger ring?
- With your other hand, bear down gently (Valsalva maneuver). How much does your prolapse bulge come down? More bulge = larger size needed to stay in place.
- Compare to the size chart:
| Size | Outer diameter | Typical fit |
|---|---|---|
| Size 3 | 64 mm (2.5") | Small anatomy, no prior pregnancy |
| Size 4 | 70 mm (2.75") | Most common starting size |
| Size 5 | 76 mm (3") | Post-childbirth or larger frame |
| Size 6 | 83 mm (3.25") | Multiple vaginal deliveries, larger anatomy |
| Size 7 | 89 mm (3.5") | Advanced prolapse, large frame |
The right-size pack — when guessing isn't enough
If you've had one size fall out and you're not confident on the next size, don't guess. The SciMed 3-Size Right-Size Pack contains three sequential sizes (Size 3, 4, and 5 — or custom combination) for $129.99. Try all three at home, keep the one that works, return the two unopened for an $80 refund. Net cost: $49.99 for the correct size.
This is the lowest-friction way to get the right size without a clinic fitting fee ($120-180 typical urogynecology appointment cost).
$129.99 for three sizes shipped together. Try all three at home over the week. Return the two unopened for an $80 refund. Net cost of the correct size: $49.99. Free US shipping, 30-day exchange on unopened packs.

Frequently asked questions
Is it normal for a pessary to fall out?
No. A properly-fitted pessary stays in place during normal daily activity including bowel movements, coughing, lifting, and exercise. If yours falls out, the fit is wrong — not the device.
Should I throw away a pessary that fell out?
No. Clean it, let it dry, store it in a clean container. If you figure out it was the wrong size and move up, you may be able to use the fallen-out size later during pregnancy or if prolapse improves. Many pessary users keep 2-3 sizes rotation.
Can I still use the pessary if I'm bleeding after it fell out?
Light spotting from vaginal wall irritation can occur. Clean the pessary, give yourself 24-48 hours without a pessary in place, and re-attempt with the correct size. If bleeding persists more than 48 hours or is heavy, see your gynecologist.
How quickly can I try a different size?
Immediately once you have the right size. SciMed ships from California with same-day dispatch before 2 PM PT, so you can have a new size within 2-3 business days.
Do I need to see a doctor if my pessary fell out?
Not necessarily. If this is your first expulsion and the fix seems clear (sizing up by one), the self-check and right-size pack approach works for most patients. See your gynecologist if (a) multiple sizes have fallen out, (b) you have new bleeding, pain, or unusual discharge, or (c) your prolapse appears to have worsened.
Will insurance cover a replacement pessary?
If you have insurance that covers HCPCS A4562 (pessary, non-rubber), replacement is often covered. SciMed pessaries are HSA/FSA eligible under this code — you can use pre-tax dollars to pay. For insurance-billed replacements, you need a prescription and your clinician's office handles the DME supplier billing.
What if my doctor says I need a different pessary type (not ring)?
If your clinician recommends a Gellhorn, Donut, or Cube pessary, these are typically prescription-fit and clinician-dispensed. SciMed currently supplies ring pessaries only.
