Going Crazy or Just Hormones

So my Aunt is watching my 1yr old for me this weekend while me & my SO are getting the house ready for our daughter to get her, I have 13 days. Well, after I got up from a nap I could have sworn I heard my baby boy talking in the living room or his room but he's been gone since yesterday evening. Anyone else experience things like this? I think it could be from the stress I'm under from being 37+2 pregnant, being separated from my boy (which I hardly EVER am), & today is my 2 year anniversary of losing my first pregnancy, our baby girl Lillian. I'm just totally freaking out & ain't so sure I wanna be at my home alone for the rest of the night until my SO gets home from his shift at 4am.
