I'm so sick I can't keep going through this

Cassie • Currently pregnant and I have an amazing 9 year old daughter!!!
I killed my baby, it's my fault I am going to miscarry. My pregnancy is not progressing and everything was going well. My husband and I got into a huge argument the week before I had my Hcg done and I got so depressed and stressed. Now I'm about to fucking lose my child and I'm going crazy to the thought that the man I married caused this. Why couldn't he be the bigger person and try not to argue or let me get upset? Now I'm going to go through my second miscarriage this year!!! This month would have been the month my baby that miscarried in March birthday! Now I'm about to miscarry my second miscarriage this month. This is super hard for me!!!! I'm literally losing my mind!!!!
