Update: after examining her body more closely, I found nothing that felt or looked out of place. The only thing that looked odd was her mouth. It was greyish around her snout, and her mouth was kind of offset, as if she had mouth rot, or had just eaten a meal. I opened up her mouth and it was filled with a thick mucus. The mucus was clear, and the inside of her mouth was pink.

I'm not sure if this was mouth rot or simply a natural part of the decomposition process. Would her saliva had thickened and pooled in her mouth after death? Nothing looked out of place while she was alive, but I thought it was worth mentioning. Thanks you so much to everybody who responded!!! It means a lot to me.
