Am I overreacting?

My mom is a big time hoarder! I mean just junky for no reason and she hates being called out on it. Lately I've been trying to show examples so she can learn to clean up after herself like after she's done in the living room to take all the stuff she brought out and place it back where it belongs. Like for example, a empty chip bag, a cup she was drinking out of a plate she just ate dinner from and it has been working. I mean she would leave hair that she's brushed out of her head all over the bathroom counter down to her blowing her nose and leave the tissue on the counter! and it's disgusting. But tonight she decides to make herself something to eat and leave everything she used out on the counter in the kitchen which was a pack of hot links, cut up onions, garlic, and flour all left opened on the counter. There has been bugs in the kitchen that I finally was able to get rid of. so I said mom you are slacking and her response was don't worry about me you should have been worried about what you were doing 9 months ago!! 💀 I'm 38 weeks pregnant!! So now I'm feeling like wow is that how you really feel about me being pregnant? Was your excitement actually a false? I am being induced in 6 days and now I don't even want her at the hospital because now I know how she really feels. And knowing me that comment is going to replay itself in my head when I see her there at the hospital. Idk what to think of it and I hope I'm not overreacting. The truth always comes out when you're upset. How would you feel about that comment.
