When to stop popping?

Just wondering my husband wants a big family I want a small one! Like maximum 4 kids my husband wants like 8 or more ugh that is just annoying I like kids but they get very annoying and when there's so many of them it's like a free for all and would drive me nuts! No way to more than 4 for me!!! (Especially cuz I have fertility issues 😉) but still wondering what other people think!
