miscarriage

On friday i was spotting, went to the dr they told me it was signs of a miscarriage ordered me to bed rest, which i did, through out the day i started bleeding more and more, with heavier cramping and abdominal pain, i woke up at 2 am Saturday morning with horrible cramps and abdominal pain, when i went to the restroom i felt something heavy come out, i had a miscarriage i went to the hospital they found no baby in the ultrasound, this was my first pregnancy at age 32. I am so broken right now i was so looking forward to my baby. I dont know how to cope with this loss I feel its my fault, for being under stress and having problems with the father of my baby. I wish i could have prevented this.
