Depressed bout not having enough room

So im 24wks pregnant with my second lil girl n we are renting a 2 bedroom townhome n i wanna make a nice nursery setup for this baby but there is like no room my daughter has one room n me n my SO have the other one n i don't feel its right to invade my daughters space right now they will eventually share a room when baby is like 1 or 2 maybe if we don't buy a house first (we plan on buying a house next april) but for the time being i don't know what to do my lease isn't up until april n we just renewed our lease right before we foundout i was prego so im lost i want this baby to have the nice nursery her sissy had but i doubt its gonna happen n it makes me disappointed in myself for not being prepared for this lil lady like we were with our first.
