The best thing I know to get a sample is a wine thief. If you don't have that, your racking cane or a turkey baster will work in a pinch. Sanitize it, pop off your airlock or carboy cap if you're using something bigger like a turkey baster. Get your sample and then seal it back up. Do that today, then do it again later in the week. If they're the same, then you COULD bottle.
but....
If you give it another week or two, you'll get much better beer. When the yeast finish fermenting, they move on and start eating up all the by-products they left behind that can cause off flavors in your beer.
More time also gives a chance for more of the yeast and any other particles (break material, hop particles, protein, etc) to fall out of suspension and collect at the bottom of your carboy, making your beer clearer and leaving you with less sediment to deal with in the bottles.
We all know waiting can be painful when you're wanting to try your first brew, but you'll be paid off if you can put off bottling as long as possible.
Give it a day and go to your local home brew shop and pick up a wine thief to take your sample with. While you're there start planning your next brew. Maybe even pick up another carboy and get started on it! It'll give you something to do while you give this one time. Then you'll have your first brew to drink while you give this one time and start your third batch. Fill the pipeline, my friend!
