how to tell your children?

I just recently had a miscarriage and have 3 children at home. ages are 5,3, and 9 months. should I tell them about the loss of a sibling? I was 6 weeks along and the baby would have arrived 2 days before my second. it seriously is killing me because I wanted this baby. everyone keeps saying that it just wasn't suppose to be and that God had other plans and that I just didn't need a third child to raise on my own since I left my abusive boyfriend.. any advice please??
