miscarriage

After 4 years of trying and losing all hope that I will ever get pregnant. I actually got pregnant. It was the happiest week of my life. Yes I said week. My hormones were tested and in my 5th week my levels were at 899 miu/ml. Three days later my levels dropped to 434. I just had them tested this morning which happens to be 2 day later and my levels dropped to 258. The process for the miscarriage has begun. I'm bleeding and crying and hating myself. I keep asking what did I do so wrong? Why me? Do I not deserve to be a mother? I could use some words of encouragement. please be nice. I wish and pray no one goes through this. Baby dust to all✨✨✨✨
