Small living space

I currently live with my uncle because DF is away for training. I have a toddler with one on the way and as of now me and my toddler share a room I have a queen size bed and she has her own toddler bed. I'm planning on moving out this summer however I will be due then and will be giving birth prematurely. So just in case how can I rearrange this room to fit us 3. I know it doesn't sound healthy and all but I'm hoping to just work around my situation until time. I have a crib that comes with a changing table my LO used before I plan on using it again to save money. any ideas
