My children were born a while ago, so I never had these kinds of tests, but I have attended over a dozen births and the support of your Dr is critical!! I have chased out the machine happy nurses and Dr.s from the labor room more than once!!
Decide what the worst thing that could happen is and face it as well as you can. Would you not have the baby?
Sonograms 'disturb' your child. The quantity of them given now days disturbs me greatly.
I would look for another DR or maybe a midwife and get some support. I wish I could give you a hug! You are in charge of this and do not have to listen to them. Do you have a labor and delivery attendant to support you? A friend or your husband to go through these visits with you? You have enough worry and having someone there to stand up for you and support you may be a big help. It is a big commitment and why some people hire Dulas.
My prayers are with you. E., you can know in your gut what is the right thing to do. My support for you says not to go to the extra visits unless you would consider not having the baby. IF your baby is going to come, (and it will be perfect!!) get this stress out of your life. Dr.s need to cover thier butts as well as thier costs.
