Kittens spay site...not normal

Tink got spayed 2 weeks ago. It doesn't look infected and was healing well until today I picked her up and looked at it and saw this weird, hard white thing (for lack of a better description) sticking out of it. I will post a photo below... Just because it's hard to explain. It doesn't seem to be bothering her in the least but definitely don't think this is normal...any ideas before I call the vet?

I believe it's an internal suture that has made its way to the surface. It'll work out on its own. You could take this picture in to the vet for assurance, but I'm pretty sure that's what it is.

Thank you!!
