Help...its killing me- advice needed

My hubby is on this so posting anon.

I have baby fever so bad, im just turned 29 years old and hubby is nearly 30 years old. He asked to try a few months ago ( I hadn't told him at that point I wanted children). We bought a house, I got a good job and he was promoted. We are stretched financially at the moment and will be for about a year because we had some things that needed done in our new house. We have a car and plenty room. I felt ready and secure. I really wanted to start trying now but he changed his mind. What do I do????
