I'm so annoyed!!

So this isn't the biggest problem, but I know someone here would relate to how frustrating this is. I flew home from visiting my mom yesterday and they lost my luggage! It wouldn't be such a pain today, except that I had such a limited wardrobe at 28 weeks pregnant and all my maternity clothes were in that bag!! I am stuck here with nothing that fits except what I wore yesterday. The worst part is that the airline said it would arrive today but now they really can't find it and I am just left hoping that it shows up in the next week!!
