The doctor told me I need to sign an agreement or refuse blood transfusion during childbirth...I said I'm against it then she said they will apply oxytocin after birth to prevent bleeding...I said I wanted more natural births...she said that everything can happen and even to save a woman sometimes they do hysterectomy...To say I was shocked is not enough... I lost my desire to give birth with this doctor...I don't understand why they even talk about such things? I am in this country like a refugee from war and she talks to me in broken English...I can't understand if she's a normal doctor or not...and should I stay with her or look for another one? Completely confused...
