I would advise against including any information about this in your CV because some employers might argue that leaving after one semester, regardless of the reason, could be an indicator of your commitment to follow through. While you and I know that isn't the case, employers have a stack of resumes and are looking for reasons to rule people out and shorten the list.
If you took the GRE or GMAT and have a good score, I would include that as that shows a commitment to developing yourself.
Lastly, when you do start up again, I would include the information but not anything about leaving due to a pregnancy or moving abroad unless the move was for work. You can choose to speak to that during the interview phase but the CV is not the place for it.
Hope this helped, have a great day!
