2 miscarriage D and C - UK

I am currently going through my 2nd miscarriage ( baby had no heartbeat at the 12 week scan)

I am due a D and C next week. Is it a simple procedure? I am feeling very anxious about it. I am at the point now where I can’t put myself or my body through this... it is one of the worst things to experience and to go through it twice is nearly breaking me.

I have a beautiful 2 year old and will continue to get joy from her every day.
