Where do we go from here?

Hi, we are feeling very defeated. We’ve had 4 miscarriages, last one 3 days ago. 3/4 in the past year, although I’m happy to say goodbye to 2018, I’m scared now Bc of how devastating it is to the both of us if my hubby is willing to keep trying. We are older I’m 36 and he’ll be 42. He has a son from a previous marriage but I don’t have a child of my own, I’m really set on trying Bc it’s something I really want, however it’s easy for him to say no Bc he’s had a child already and experienced it. Where do we go from here? 😢💔😪
