Looking for support

I had my 20week scan yesterday and found out I lost our baby at 17w. I knew something was wrong when the baby was measuring so small but then when she went to the heartbeat she pulled everything off the screen and said she'd be right back. I never even got to learn the baby's gender. I have a D&C scheduled for Tuesday because the induction had so many risks for me. I have a 4yr old that is mentally more like 6 and I have no idea how to tell him. I'm sure my 2yr old hardly understood we were pregnant. The only think I'm thankful for is not telling our extended family out of fear of this happening. I'm trying to keep going for my boys but all I want to do is sit in my room and cry. My husband has been so supportive and bought me my favorite food last night.
