Well, she is definitely on the end of when women have babies and actually past. Natural pregnancy at 47 years old and one that goes to term is rare. Things to worry about even if the pregnancy continues is birth defects that as the pregnancy progresses they will test for. Eggs become of less quality as a woman ages. Those are real concerns. However, she's pregnant and you two sound happy about it. So, enjoy life and take what comes. Advanced maternal age does mean that she will be in a high risk category and pregnancy may be a bit more difficult on her physically. If she has had other children, she will be able to compare. I had my kids younger than her but what was considered older. I made it through just fine. :>) So, congrats. How far along is she?
