Missing my baby😢

Some days I'm okay, then there's days like this when all I can think about is how far along I should be and how big my baby boy should be and how much stronger his kicks should be. I miss him like crazy. I don't understand why this happened to my baby and I, and it's not fair. My heart hurts for him and I just wish I could have him. Just venting, while trying to cope ... It's been 3 weeks now since I lost him. When will it get easier?
