miscarriage the same as contractions?

Firstly I started bleeding heavy followed by really intense cramps 2 seconds apart also so much pressure and almost like electric shock pain down there.
Is this anything like labour pains.?
I have a high pain tolerance but this made me cry like a baby and cripple over in pain.
Horrendous!!!!
Once I passed the baby the pain went!
