Obviously there are so many different needs to be met, and different philosophies out there. In the end, it is YOUR body, YOUR baby--and yes, educating yourself as to what test is being recommended, ask questions, use some common sense, etc. I think there can not be one philosophy on this. Open your eyes, ears, and minds....don't do just because the dr. said to--but don't not do just because you don't trust western medicine!
My first pregnancy I had pre-eclampsia (very serious condition)--was put on bedrest, and they wanted me to stay at the hospital. I still had at least a month before delivery. AT that point, I worked in hospitals--knew myself enough to know that would be more anxiety producing than if I was at home on bedrest. I literally battled with my dr.--told him if he was keeping me in the hospital--it better be in the pysch. ward, because that's where I would end up! He let me go home--worked out far better. Even the dr. agreed!
Bottom line--inform yourselves! speak up for yourselves, but don't discount that the dr. may actually have some education and knowledge too!
