I want to have another child?

I have to admit that if my doc said I might not want to have another, I would be stopping to think it over. Did you ask her why she did not want you to? If is medical, that is something you need to take into account, as you have five children to take care of. I am sure that she is not giving you a personal opinion, so there is likely to be a reason for her to be hesitant. Discuss the risks and see if they are what you are willing to deal with. It is important that you stay healthy for the children you have at home too.
