41 weeks, still birth

I had an appointment on the 1st of July and everything was perfect! Baby girl was around 7 pounds and her heart was beating so strong. Then on the 3rd I realized I didn't feel any kicks on her normal schedule. When I got there they couldn't find a heart beat and it was too late. I am devastated!! I've been trying with my husband for 4 years and this is our first pregnancy. I'm starting to think it isn't meant for me to be a mommy 😩 I don't know how to come back from this. Every where I turn I see baby blankets or a crib or diapers. I just needed to vent.
