Hello! Like many of the women here, my tumor was thought to be estrogen-sensitive also. I was diagnosed when pregnant w/my third baby, had the surgery when she was 2 months old. I had a natural child birth with her which was my best labor and birth. ( I had four babies) I became pregnant four years post-surgery, and had the same concerns. My doctor said it was fine, and I went on to have a normal, drug and intervention-free birth (not high risk) in a free-standing birth center with Nurse midwives, and was discharged to home four hours post-partum. I will admit the pregnancy was more difficult due to my disabilities after the surgery. I was more fatigued, dizzy, etc. I can't remember if my headaches were a problem, but they are always a problem so I imagine they were. My migraines increased after the birth of my fourth. I am now pregnant with my fifth, and I feel pretty terrible again. Most important is to have lots of support and take good care of yourself.
