Its not recommended. I have heard that it could "stir things up" unneccesarily, or even introduce infection if your hands are not properly cleaned. Plus you don't really know what you are looking for as you are not a trained medical proffessional. Just wait for your next prentatal visit and ask your doctor or midwife to check you!
Dilation also does not always indicate that labor will begin right away. I was dilated to almost 3 cm. with my youngest daughter for three weeks, and even then I had to be induced.
