Always keep all of your prenatal appointments, and talk to your doctor about any concerns that arise.

You're bound to run into some awful ones, with women talking about how horrible childbirth was or about this or that terrible symptom they experienced. You want to try to avoid as much stress as you can while pregnant, for the sake of you and your baby. Reading stories about other women's poor experiences will only cause you unneeded stress.
