Still birth

I just had a still birth April 20th 2021 and I’m having a hard time dealing with it. The doctors don’t know why it happened.. I was healthy and baby was healthy and I had no pregnancy complications.. she was fine one minute the next my water broke then she had no heartbeat. Anyway, I came on here because I just wanted to know that I’m not alone. I thought it might give me hope if I came across some rainbow baby stories. That way it doesn’t feel like it’s the end. I hope I can have a healthy baby and pregnancy after this. This is very discouraging if I can be honest
