Just had baby 7 days ago and I have chills. What do you suggest?

See your doctor. Have you taken your temperature? Do you have other symptoms? Is the baby ok? Check with the ob/gyn or your family doctor.
Call doctor. I would recommend that you start by checking your temperature. If your temperature is 100.4 or greater, you need to notify your physician. You might have an infection in your uterus or breasts that is causing the fever. If you do not have access to a thermometer, i would recommend that you notify your physician anyway to schedule an examination.
