What is a natural miscarriage like?

Jenna • TTC#2. Have an almost 2 year old daughter. Miscarried at 10 weeks in April 2016. Chemical in July 2016.
Started spotting last night. The baby died almost two weeks ago and my body has finally recognized it. What should I expect? I read all these stories online about people seeing their dead baby in the toilet, others who just have a really heavy period. Some who say the cramps are more like labor contractions and hurt so bad, others that say it wasn't painful. I'm sure it's different for everyone, but what was yours like? I'm very nervous!!
