DH and I have been trying to conceive our first child for 9months. I'm 32. He has just been offered work out in China for 3-4months. Although it would be fun, it's not actually a great opportunity for his career. It's just freelance work similar to what he normally does. I have said I don't want him to go because for me the priority is to get me pregnant. He can go away all he likes once i am pregnant but i really don't want to waste 4months of this year not being able to try. Is this unreasonalbe?
