2nd missed miscarriage in 8 months


I sit here wondering, how is this happening to me again! Why does my body suck! I went in Monday for an 8 week scan, 12 days before that I had a 6 week scan and saw and heard the heart beat. 126 bpm. I was confident that this was it my rainbow! But yesterday we went and it grew! It looked exactly how it was supposed to, but it had no heartbeat! How is this even possible! How can it grow so much and just stop? I feel like a failure and maybe I am not meant to be a mother and these are my signs. My thoughts go out to anyone who goes through this, life is just not fair sometimes
