S/O help

My fiance and I just had our second miscarriage last month. Our first was back in March. We got the okay from the doctor to try again if we want too. I'm ready I want to try again I feel like if were going to lose another one itll happen whether we wait or not. But he doesnt want to try yet. He says hes not emotionally ready. He doesnt know I want to try again because when he told me he wasnt ready I felt like if I told him I want to try again now it would be insensitive and possibly make him feel like im putting myself first. I feel like my closure will come from a healthy rainbow baby. I dont want to hear opinions about trying again so soon I just want help on ways to talk to him about how I feel without coming off insensitive. I feel like this isn't something we can compromise on because it's not like he can pick a date and tell me that's the day hell be ready and feel better because he cant just decide that day but I want to try again. I'm just at a loss and I'm never at a loss for ways to talk to him.
