Why is this happening

I'm so sorry to hear this. Unfortunately sometimes there are no answers as to why. Just know it is absolutely nothing you did or didn't do. I miscarried in November last year, and I spent so much time looking for a reason and blamed myself for silly things like staying up too late. But that was just torturing myself. It is a tough time, but it does get easier. 

Sorry for your loss. My prayers are with you.🙏
