Strange things

Maybe you've heard that pregnant bodies do all sorts of things, maybe you haven't. Here are some of the weird things I've noticed so far:

1. I have a strange rash/bumps on my upper arms. I think some people have these all the time, but I don't so it's weird to me. They don't itch, are not red or pimples, just bumps. 
2. I have a lot of dreams. Last night's dream was about an awesome food buffet. I was having a great time until the hubs woke me up. 
3. I am starving. When I get hungry, I can usually wait a while until I eat. Now, I start to get shaky and a lil nauseous if I don't eat pretty soon. I also can't eat very much. If I eat too much, when I burp I throw up in my mouth a bit (gross, I know.) but that's apparently because the valve that closes at the top of your stomach gets loose. 
4. I can't walk fast. I used to walk super fast to get to a meeting at work. Now, I'm the slow poke holding everyone else up. It's really annoying to start panting immediately.
