8weeks and mostly miserable

I'm 8wks pregnant with my first baby. I'm starving all the time but gag or throw up everytime I eat, my back hurts, my breasts are already swollen and painful, I feel dizzy sometimes (probably from not being able to keep enough food down), and my poor husband is getting the brunt of my mood swings. And don't get me started on the uterine cramps....

I read that it gets better after 12wks, is that typically true, I want that pregnancy glow :) please tell me it's not going to be like this the whoe time....
