Husband says no

I’m currently one week post ectopic pregnancy by surgery removing of right tube.. I discussed with my husband about TTC maybe in February or March. His answer was no he says he couldn’t take me going through something like that again. I feel so broken and sad over this. While I was pregnant I was so happy to give my little one a sister or brother and it got taken away. Still grieving the loss, but I know in my heart that I want to try again and he doesn’t.. The thing that scares me the most is time. I’m an older mother I’m 37 years old going to be 38. the sooner I get pregnant of course the better. I just don’t know how to convince him.
