Aneros ever get lost in rectum?

Here's the story. One night, about three months ago, I had the peridise inserted (smaller one) and had a few glasses of wine. Didn't get drunk or anything, but fell asleep on the couch for a few hours. I have a vague memory of waking up, going to the bathroom (removing the peridise, or at least I thought I remembered that), then going to sleep in my bed.

A few days later I went to get the peridise, and it wasn't in the usual keeping place. I worried that it somehow got left somewhere embarrassing (common laundry area) or had just dropped in the apartment and would pop up at the worst moment (when a guest was over). But I looked all over the apartment, obsessively, and never found it.

Here's what I think happened: I was removing the peridise that night with some toilet paper in my fingers, as I always do as a cleanliness buffer, then in my tipsy and sleepy state, mistakenly threw the peridise in the trash bucket with the toilet paper. I may have even realized I did this at the moment, but got distracted, never remembered to fish it from the trash and went to bed. The trash was emptied a day or two later, before I went looking for the peridise, so if that's what happened it's gone forever.

Anyway, that's what I thought happened. But recently after happening upon some news story, a horrifying thought occurred: could the peridise have disappeared into my rectum? Obviously, I'm hoping the answer is an emphatic "no." The flare on the base is pretty wide and pointy; it seems impossible the thing could unknowningly get sucked in. Even if it did, there would be obvious pain and discomfort, stool would not pass easily, etc. Not to mention I've been running three times a week for months, which would probably agitate anything stuck way up there.

So someone please just tell me, no, there's no way a peridise could accidentally, unknowingly get stuck in the rectum for three months, so I can put this weird thought to rest.
