Does anyone dislike pregnancy so much that they stopped having kids or decide to adopt future kids?

We’re pregnant with our first child and believe me when I say we want this baby so much. We went through fertility treatments and everything. We were so happy to find out it worked and that we’re pregnant. I’m almost 7 weeks and I’m so miserable with symptoms and have been regretting everything even though I know we want this baby. I’m told this is normal? But it still makes me feel a bit guilty, but I’ve disliked pregnancy so much that my husband and I have discussed potentially just having the one kid, or adopting a second kid. I was just wondering if other people have felt this too? I’m sure once you have your baby it’s “all worth it in the end” but it’s not great right now. And I don’t want to go through this again.
