A mother's suffering

Here's my new baby. I'm quite proud of this one; I feel like I've taken another step forward in my development. I've understood and applied many things that I was lacking until now.
The design of this monster blends human and arachnid characteristics, like the result of an experiment gone wrong. But this creature, with its multiple spider arms and legs, seems to be suffering. Its lower body, now unusable, is dragged along the ground, injuring its legs—legs that were once chained, probably to prevent it from escaping. And finally, like some spiders and toads, this creature is carrying its offspring on its back, or perhaps... on its back? These multiple monstrous fetuses are developing and piercing its skin.
Despite all this, I doubt any group of adventurers would want to cross paths with it in a dungeon.
