First off, taking care of yourself and that baby is #1 on your list of things to do!! Take a deep breath and relax. Don't stress yourself or that baby out. You need to keep your blood pressure down. Let the insurance company handle it. Let the HR department handle it. Let the police handle it. If the doctor approaches you again, let her know who she can speak with as you are pregnant and the stress resulting from her actions are now effecting your pregnancy. Let the HR director know that this woman is harrasing you and that if it continues or starts causing more issues with your pregnancy, that there will be bigger issues for them to deal with than a hit and run on their property.
