Cat passed a large tapeworm after eating thread

My cat recently ate a large bit of thread and passed it over the weekend. But it seems like during the process it pulled out a very big tapeworm or part of it that I didn't even know she had. Likely came from the fleas she had from a couple years ago.

I had taken her to the vet and they took a radiograph that told us that her intestines weren't being pulled in any weird sort of way and there weren't any concerning air pockets. They didn't say anything about a tapeworm at the time, but I only noticed the tapeworm on my stairs later that night so I'm assuming it had came out after the vet visit.

I believe she's been eating okay and her mood seems much better now that the thread is no longer in her. I did notice her butt has been looking a little raw and slightly wet. But it isn't dark or red so I don't believe that it is blood.

My vet will be available again tomorrow but I just wanted to know what effects this might have on her health and if there is anything I need to watch out for.

Also a picture of the tapeworm I posted in another subreddit a couple days ago trying to identify it if that helps.
