How? Why?

Hi ladies. I'm still bleeding. I was 5 weeks, 4 days on Saturday when I began this bleeding....I had three tubes of blood taken at the ER Saturday night....my levels were only 132.  Today, Tuesday, I saw my OB GYN for the first time. He sent me back to the hospital for another blood test...two tubes today. I have to call my OB GYN in the morning for my blood test results. I've been bleeding and cramping since Saturday. I've cramped since I found out I was pregnant, but the bleeding scares me. I'm sure my baby is gone and I have yet to grieve, I'm just numb. I wanted my baby so badly. My heart is just broken 💔💔
