so uncomfortable!

Lauren
So I'm ONLY 17 weeks and I feel like the past two days, I've felt beyond uncomfortable. 
I have a siactic nerve in my back.
I can't sleep
I'm still throwing up. 
And when I sleep I can't get comfy
Today I feel like a very very heavy sensation In my uterus. 
I keep getting headaches. 
My mom and sister both had easy pregnancies. I just want to feel comfortable! But it's only going to get worse.
