Not sure what to expect from a miscarriage

Pregnant for the 2nd time, and this baby unfortunately stopped growing, my body has been pregnant for 9 weeks but baby is measuring 6+1, never experienced miscarriage before and I am waiting for my body to take care of things naturally.. just wondering if anyone can offer any helpful info or give me an idea of what I should expect. I have had no cramping or bleeding at all yet and I feel Kind of nervous about going through the experience and there is no one in my life I can talk to about it.. thanks everyone for the input.
