Miscarriage

I had a miscarriage starting January 4th. I just now stopped bleeding. The day I found out for sure and heard the words from my doctor, i just sat there. I couldn't breathe and i just froze. I already knew but hearing it from the doctor made it so much more real. I couldn't even cry. I've held it together and have cried a few nights here and there but I haven't cried non stop. I have 2 other children I have to be strong for but it seems the more time to go by the more it sets in that this is real and my baby is gone. I feel myself getting more upset the more time goes by than better. I'm also finding myself upset to want to be pregnant again. Is this normal?
