My 20 week scan is next week, and dh can't come. (covering for colleague, v important work meeting, am v pissed off with him but that is another story!) So, should I go alone? The only person who can feasibly come is my mum, but I'm really not sure whether to ask her. Part of me feels if dh can't come no-one else will do but maybe that is just the pregnancy hormones talking!
