Can you show at 7 weeks with twins? //dreams

Emma
Hi guys! I am a first time mom to be and wondering if I should make anything of this. I had a dream about our first ultrasound and them showing us there were two babies 😍 have any other moms out there had dreams like that where you were pregnant with a single baby? Just wondering if I should make anything of that. 
We get our first ultrasound in about 2 weeks so I am anxious to find out!! This will be our rainbow baby since we lost our first in November 2015. 
Also my husband was notice that I kinda of have a bump ( aside from the bloating I think, I am pretty petite) but is it too early to show? 
Thanks for your advice!!
