I have had migraines (with auras) all my life and had successful pregnancies. My sister had migraines only when she was pregnant and had successful pregnancies.
On the other hand our father had migraines all his life and had multiple cerebral infarcts in his 80's. We were told then by his neurologist (that studied strokes) migraines are indicative of strokes later in life.
So go ahead have your family but get proper care through out your life.
