Feel so dead inside. My little baby gone too soon

Emily
This is going to be long but I need to share it. 
My husband and I decided to try for a baby. This was to be our first child. I researched prenatal care, started on vitamins, figured out finances, And had my paragard IUD removed. 
3 weeks later my period was late. I was elated, it's unlikely to get pregnant on the first month of trying. But 9 pregnancy tests confirmed it. I was going to have a baby!! 😢
Everything was going spectacular, only mildly nauseous at night, not super hormonal, work was supportive (work at a veterinary clinic and have to report pregnancy for safety reasons), our family's were excited...
 
Last Sunday I noticed some light pink discharge when I wiped. Called my doctor who wasn't too concerned since DH and I had just had sex. It didn't go away and by Wednesday it was fresh blood. 
Went to my doctor Wednesday. No embryo seen, sack measured 4mm, smaller than it should have been at 7 weeks. My cervix was closed. Doctor guessed the baby may have been younger than I thought, and may have subchronic hemorrhaging. Gave me a 75% of a healthy baby. 
I knew deep down that my baby wasn't ok. I can't explain how, I just knew. Lost my little baby yesterday night. My heart is broken I don't know how to move on.... I knew there was a risk with every pregnancy, but why my first?!?! I'm so lost and broken 😢😢😢😢😢😢
