Why me agian?

Man I can't even explain how much I hurt right now... we tried for 2.5 years after our devistating miscarriage at 14 weeks. We finally got pregnant. It was one of the happiest days of our life. Made it to six weeks bad cramping all day. When I got home from work went to the bathroom and my worst fear happend... I started bleeding. My husband rushed me to the er. As soon as I went to do a urin sample we lost our rainbow baby. I am in so much pain emotionally. I want nothing more then to have a baby with my husband. We are good people, we have our life stright, we are stable and in love. Why does this happen to the best people. Sorry for venting. Just feel so lost right now...
