Trigger warning miscarriage

So I had posted on here last week I found out I was pregnant with #2. Well Wednesday I had went to the hospital to get blood work done they told me my level was only 23. Friday I started bleeding and last night I went to the hospital cause I couldn’t deal with the pain and they ran tests my blood level for hcg was a 6 and they did an ultrasound and couldn’t find anything in there. My question is how did any one else who went through this deal with it. My hearts literally shattered even though I was only 5-6 weeks. I got really excited for my 17 mo to have a brother or sister. I don’t know how I’m supposed to grieve this. Any encouragement or tips would be helpful
