How do I talk to him?

So I've had two miscarriages in the past with my partner I am with now. After the last miscarriage he just decided to stop trying for kids altogether. He bought condoms which I am seriously allergic to, I'm not happy about using them but it's the only way. I get the worst symptoms afterwards and it puts me in a terrible mood. I really want a baby and I know deep down he does to but he is scared and worried about money. I can't keep going on with these stupid condoms, I'm going to end up with serious damage soon. I'm not going on the pill because I took that when I was younger and made everything worse. I'm not preventing a baby. How do I speak to my partner and tell him that there is no right time and that I really want a baby? 😔
