Boyfriend doesn't want to TTC after miscarriage

I guess I'm trying to find some support from people who have been through what I'm experiencing. I had a miscarriage at about 7/8 weeks along. I am devastated and heartbroken by what has happened. My boyfriend and I were extremely happy and looking forward to being parents and raising our baby but now after my loss, I am yearning for a baby. He wants to wait a while until I'm out of college which will be years but I want to try again as soon as my body has healed. I love my boyfriend but am very heartbroken by what he is saying. Has anyone else experienced this? Thanks in advance.
