Spouse doesn't want to try again

My bf and I recent had an ectopic pregnancy and I lost my left tube. I'm 30 and he's 44. I have a 9 year old daughter. 

The pregnancy was a surprise but a welcomed one. He's wanted a baby for a long time now and this was his first pregnancy ever. 

We have been dating almost a year now but it feels longer than that. Just natural being together so the time frame doesn't bother me. We have some home improvement we wanted to complete before adding to our family. We do basically live together already. Just never officially had a move in day. All of our stuff is at his place. 

I lost my job 2 days after my surgery for the ectopic surgery. But I have interviews lined up and know I'll have a job soon. I started working part time at the animal hospital three days after surgery so I wouldn't not be working. 

After I recover I want to try again next month. We agreed I would only start my medication (adderall I was on for 7 years before pregnancy) at a very low dose to hold me over and I wouldn't take it daily. 

Now out of nowhere he made the decision that he wants to wait and get the home improvements done. After we agreed to try next month. It's just what he wants now and nothing I've said was taken into account. What do I do? I'm sad not to be pregnant and it doesn't help our couple friend is pregnant and had the same due date as me. How come we have to wait now just because he said so. I feel sad and a little anger my feelings were ignored.
