confused

I don't know what to do. I've been thinking alot about trying again but like I said before I don't think I can handle another miscarriage. I don't know if I want to go through the stress if I do get pregnant of fearing everytime I go to the bathroom and what I might see. Am I being selfish. I know other women on DS would not even have to consider trying again they would do what ever they had to do to get pregnant. I guess I'm just not as strong as everyone eles.
