feeling guilty

I got pregnant unexpectedly and was going through some rough times. I wasn't sure of what to do with my whole pregnancy but every day that went by I was getting more attached to it, during my 6th week I got into a huge argument with a family member and the next day I started to bleed, I went to my doctor to find out I had a miscarriage. I feel like it was my fault for stressing and arguing so badly that day. It has been a week since I lost my baby and I still can't forgive myself.
