What right do I have???

So in thinking about what I want to do and what I am planning right now as far as my birth goes I am at peace with it for the most part. The only thing I am not fully at peace with is of course what is always the problem. What if. So in thinking about what I would do incase of transfer and if I have another c/section and have any kind of complications after I sit here and think about how it effected those around me last time and I think hmm what right do I have to put everyone through that. And I am not just talking about my extended family. I am talking about those who were here taking care of me and my kids when my fiance was at work. The only ones I see fitting in to this picture is my children of course, my son was so terribly worried about me last time and with him already having severe anxiety this didn't help him much at all. Then there are my youngest. My oldest daughter I know was effected in some ways as I think she knew mommy wasn't ok and then there was the whole not being able to pick her up for many weeks and she so wanted me to. Now I have my youngest, and she is sooo needy. Way more so then any of my other children. How would she handle mommy not being able to pick her up at her every whime? My fiance bless him has already stated he doesn't want me worrying about him, that even though it was hard on him he knows it was way harder on me and he pulled through it and thinks if anything like that happens again we all will be ok and get through it like before. I know he is right. I have gotten through it already now 2 times yes it will be very hard emotionally and physically but I will get through it. Then the only other person I worry about is my mother. She was there everyday that she could be to help out. Weekends, some days after work in the very begining she came to help till my fiance got home from work. But really what right do I have to possibly put all these people under such stress. There are a lot of people out there who would tell me not to worry about what "family" thinks and just do what I feel is best for me. Now I am not saying that anyone who takes this approach is selfish but for me this is because my choices will directly impact those people. So I choose to do what I want to do and if it doesn't turn out then those I ahve named will end up being there to help me pick up the pieces. How fair is that to them?
