Agh! Chubby cheeks and double chin :(

Kelsie
Please please tell me this is just water retention!?!? 
In the last week my face has puffed up and I have a little droopy pocket under my chin :( 
BP is good, I've exercised my entire pregnancy, eat well (most days) and have gained about 30-35 pounds. 
Feeling so discouraged in these last few weeks :(
