Starting to stress

So I’m 36 weeks and me my bf and 4 kids live in a townhouse but currently got a house! We were supposed to move in June 1 but now we can move in at the end of this month if our land lord can get it rented which ima have to show for her while we live in it.. I’m starting to get stressed cause idk if I should start packing up lil things or if we are even going to b out at the end of this month when I have a nb that can come any time I hate not knowing...🙄
