You likely won't start showing until you are 4-5 months...normally that is when women start. You might just need to buy a pair of jeans that are just one size bigger until then.
I'm in Canada, and I shop at motherhoodmaternity.ca I don't know where you live, but have a look anyway.
This morning I was craving smores again so I made myself a couple. Now just an hour later I want curried rice(with HOT curry). With my first pregnancy I craved salty things, but nothing really specific...with this one, they are specific! One minute it is potatoes, the next is fried...
