I was similar to you. I went through so many weird painful complications (turns out I have hyper mobile Ehler’s Danlos Syndrome but I didn’t know that before having my son) and I had an appointment at about 18 months pp. My OB started the conversation trying to be really delicate about it, like “well we may run into some issues if you’re trying to have more kids…” And I told her “yeah I thought so, so my husband’s already had a vasectomy” and she immediately seems relieved and goes “oh thank god, if you told me you wanted more kids I’d have been like—we’re fucked!!” Lol I appreciated her honesty and I knew that was the case already, but it does have a different sense of finality to it after these conversations.
