I'm Looking Into Becoming An Obstetrician/gynecologist But I'm Also Worried

I'm looking into becoming an obstetrician/gynecologist but I'm also worried about one thing in particular. I am very excited to become a mother and have a family life. I am concerned that my future career will make me too busy to make a stable family and be present in my children's lives. I am wondering if you have any advice about this issue.
