Husband Getting Vasectomy

My husband is getting a vasectomy today and I find myself having mixed feelings about it now. I should start off by saying this is something we talked about at length before deciding he would do this. We have 3 beautiful kids. Our hearts (and hands) could not be more full. I think the fact that it's really going to be permanent, we will not have any more kids, I will never be pregnant again, it's just really getting to me. And the plus side I'm super excited that I will no longer have to remember to take the pill 🙌🏻 anyone else done having kids and have made it a for sure thing?? I find myself thinking maybe we could have one more, but then I feel like slapping myself and saying are you crazy woman??? Please tell me I'm not alone....
