He wants another baby

My boyfriend really wants another baby. We lost our baby a few days ago and my boyfriend is really upset about it but he is already talking about wanting to have another baby. I’m not sure if I can handle being pregnant again right now. I’m kind of scared of losing another baby. He’s really sad about loosing this baby but he keeps talking about how much he loved it and just wants to be able to hold one and love on it. Idk what I should do. I want another baby I just don’t if I can all that again. Opinions? How should I tell my boyfriend I want to wait? (I told him I didn’t want to be pregnant again right away but I think he’s hoping for me to be pregnant again this year). Thoughts? Advice? Thank you💕
