16th week

I'm just starting my 16th week and at the frustrating stage of being to small for maternity clothes, and to big for my normal clothes. Still having a very hard time sleeping, 4 nights in a row now I have slept less then 6 hours (which isn't good for me, or anyone around me :) ) I will talk to my DR next week to see if there is anything I can do, for now I plan my weekend with almost nothing to do so I can catch up on rest.
