I would say that it depends.
You say you're worried emotionally.
If it is because you are worried that you wouldn't be able to love another baby the way you do your 1st... I think a lot of women can't imagine having the same intense feelings of love for another child as they do for the child that they already have and adore. I can tell you though, as a mom of 4, that your heart just grows.
If you are worried because you're afraid you won't be able to juggle everything with the care of 2, you'll figure it all out. It can be a little rough at first, but you develop new routines based on what you find works.
If you really don't want a 2nd, but you are worried that you will disappoint your husband, that's different. You have to be honest with yourself. Wanting a baby, but being afraid and not wanting a baby, but feeling pressured (just because you know your husband wants another) are 2 different things. If you are only afraid, I'd tell you to go for it. If you feel pressured, but don't want one, I would recommend not having another.
Maybe your feelings will change down the road, maybe they won't, but IMHO you should only have a baby because you really want to.
btw- I also had a horrible delivery with my 1st, and opted for a c-section with my others. Much better :)
