I've been advised to speak to my supervisor prior to starting to ttc to try and sound him out and see what his view on things are. How do I bring it up? When I was in a full time job I always knew that when we started ttc I wouldn't tell anyone until we'd actually conceived and had the 12 week scan. But now I'm doing a PhD it seems most people advise to consult supervisor first. Anybody else been in this situation or have any advice on how to bring it up?
