Losing a baby (FEEL FREE TO RANT HERE)

My husband and I have been trying for a baby for about a year now. I had a miscarriage and it really devastated both of us. Just yesterday he was on the phone with me (he's away at boot camp) and he asked "how far along would you be, Sage?"  So quietly I barely heard him. With a heavy heart I told him I would be almost 5 months pregnant had I not lost the baby at 8 weeks. I could hear his voice crack when he said "I would have been a dad in a few months. I should have been a dad." It was like a pain I'd never felt before. A worry that I won't be able to make him a father. It's been so hard for us losing Sam (we named it to get closure, gender neutral name)
