Most doctors would give you a go ahead if it is absolutely medically necessary - I am assuming it is not in this case. On the other hand, some doctors would advice that it is now safer with modern X-Ray technologies and using protective shield, and particularly when the pregnancy is at an advanced stage.
We went through it about 7 months pregnant and our baby was delivered safely and healthy.
Doctors would rightly advice you, but the final decision is yours.
Cheers.
