I got this from the French CIC website. I believe the only complications due to pregnancy is the chest xray. Once that is done, you can land.
Is a pregnant woman obliged to have any X-rays done.or can she be exempted?
A chest x-ray is an obligatory part of the medical results. Pregnant women may submit a chest x-ray taken within the 6 months preceding the start of the pregnancy so long as the applicant's identity and the date of the x-ray are printed on the image itself. If such x-ray is not available, there are two options: you may decide to have the x-ray done with a protective apron or wait until after the child is born. If you chose the second option, please let us know, mentioning the expected due date. Do not forget to inform us of the birth of the baby by sending us a copy of the birth certificate
