meaning of dreams pregnant

Recently my older sister and soon to be sister in law have became pregnant and everyone keeps asking me if i am gonna have any more (i already have 2 boys) and i keep telling everyone no. But i had a dream that i was pregnant with a baby girl and my house was a wreck!! (at least it was assumed to be mine) and i ended up having delivering the baby by myself! ANd when she was born the umbilical cord was wrapped around her neck and she was turning blue. I had to unwrap it.
