Chances are you'll get an alcohol 'buzz' for a while, possibly a headache, maybe some stomach upset.
How drunk you'll get depends on how much you drank, how quickly and your body weight. If you're a 100lb girl and you quaffed a half glass of wine, you'll definitely feel drunk. If you're a 120lb girl and those six sips maybe added up to, say, 3tbsp (about 1/8 cup), you may be a bit tispy.
Either way, drink water. Staying hydrated will help your body metabolize the alcohol and decrease the odds you'll get a headache or feel nauseous.
Oh, just so you know, your body and especially your mind is still developing until one hits about 25 or so. While catching a buzz can be fun, the more intoxicants you take in, the more those intoxicants are going to impact your development.
What you do is your choice, but you may want to keep that little tidbit in mind
