Why so hard


I have had 2 miscarriages before, but this one! We seen the heartbeat.....how does it just stop? After being told everything looks great a week earlier....I just don’t understand! I passed this baby yesterday and took it into my Doctor to have it examined! I struggled so much attaching to this pregnancy with fear of hearing those three words ( THERES NO HEARTBEAT) Then they said them, I really don’t know how I will ever be able to enjoy or attach to a pregnancy! My fear will always be there....what should I do?
