Lost my baby girl at 32 weeks.

I don't know what to do I feel just completely broken and devastated. 
I had this app for about 2 years now since I was pregnant with my first baby, everything was perfect with no complications just like this time.
They said she was perfectly healthy, she kicked a lot and they said she was all good. I then noticed she didnt kick for a day or so and went to the doctors a day later and they just couldnt find a heartbeat, I had to give birth to her which was the most horrible and hurtful thing ever I can't describe it.
I feel just broken I can't realize it I still cannot look in my husbands eyes and I can't stop crying I just feel like its my fault and its been days now. They said me giving birth to her would help me accepting it but I just died a million times I really don't know what to do.
