Controlling mom?

My SO and I just got our own place together last Wednesday and we have been doing all of the moving ourselves. I’m 33 weeks pregnant so it’s been mostly just him. My mom calls me like four times a day and asks what we’ve got done and when I tell her she freaks out and says well that doesn’t sound like a lot. She keeps trying to tell him and I how to do things and it’s getting really exhausting. I don’t even want to answer her phone calls. She stopped by on our closing day she dropped off boxes of pans, silverware, bowls, etc. When we opened them it was completely rusted silverware, pans full of food caked on them, and bowls that I know she would never use. She’s been going through everything in her house and giving us all of the stuff she doesn’t want snd cluttering up our brand new place. We explained we are going out and buying brand new sets of everything. It’s like she’s doing a clean out of her house and just giving the junk she would throw away to us for us to do. She knows the stuff she gave us is bad too because she told us to just throw it away if we don’t want it. She doesn’t understand she’s making our moving in so much more stressful than it has to be. We don’t want to have to be sorting through boxes from her throwing stuff away when we have enough of our own unpacking to do! We’ve been here for 4 days and she’s called me every single day and all that happens is her and I argue (it’s her who raises her voice at me and insults my SO) which then turns into my SO getting mad that she’s putting that stress on me. I don’t know how to get her to back off because I’ve explained to her how stressful moving is and how we need space right now and she just said “like hell you do. I’m coming over anyways and bringing more stuff”
