Early pregnancy months are the most important ones and I'am pretty sure that if Mary knew she was pregant she wouldn't ski! Pregnancy women shouldn't make any sports in the early pregnancy months those are the most important months for the evolution of the embryo also you could have a detachment of the placenta,
all of this in the early pregnancy days and months so I'am pretty sure that Mary is a very wise women and she wouldn't ski if she was pregnant
