I can always defer for a semester or two till i know how i cope with ivf.
Personally this is what I would do, I would definitely not give up the course entirely. When I did IVF I changed my working life and put study on hold and looking back now it was a huge mistake. Professionally I have really put myself behind the 8 ball and in the last few years I have had to work very hard to rebuild my professional life. (particularly as we where unsuccessful)
Plus it might be good because it might give you something else to focus on if you (god forbid) became a long term IVFer.

Good luck
