Can my son sense a baby is coming?

maria
Ok so lately I've been peeing a lot and its puzzling because my water intake does NOT equal what comes out, lol (not a UTI). My husband has been really REALLY annoying, but he hasnt done anything( i felt like that towards him when i WAS pregnant). My son is 3 and has always said he doesn't want a sibling, he'd rather have a puppy! BUT yesterday out of the blue he started demanding a sister/brother if not both i cant tell. My breasts have been feeling fuller and bigger. Ive been so EXHAUSTED by 3pm, that i NEED a nap. Other symptoms as well, Im testing tomorrow morning, (six days before my period) I need input basically, am I over thinking? Should I get my hopes up? Thxs for reading and for your input.😃
