Creeping Charlie or ground ivy is a difficult lawn weed to control. You can spray it with a selective broadleaf weed herbicide. Late summer and early fall are the best times to spray herbicides on extremely difficult weeds like this. Spray twice, about 2-3 weeks apart. If you can find the herbicide Speed Zone it is very effective on it. Always spot treat, don't spray over areas that are not infested. Hand pulling also works fine for a small infestation but you must be sure to get the roots, so work when the soil is moist. Also, see http://extension.umd.edu/hgic/ground-ivy
If you haven't tested your soil in the last 3 years you should do that to make sure the pH is in the proper range for grass. Also, make sure you are fertilizing in the fall and mowing about 3- 3 1/2 inches. The following is our lawn care information, extension.umd.edu/hgic/lawn-care
