Hello,
From previous experience with my clients which were pregnant, we do usually encourage them to wait until the birth of the baby and take the ex-ray afterwords.
I believe that until your medicals won't be completed, the officer won't process your application.
Also, according to the Migration policy, they can't make you take the ex-ray while pregnant and it needs to be postponed until the birth.
All the best.
