I'm scared :(

Akala
So today I was examing my body and I noticed I have a white substance looks like a ball inside my vag and when I push the muscles it kinda hangs out like a piece of meat. And has a hole with a line in it. I'm so scared and I need help determining what it is. If anybody know what it could be please let me kno the feedback. (Sorry if I was to graphic) :/
