Ups and Downs

Some days I feel so lost. We found out on 2/14 our baby boys heart had stop. On 2/19 I had a D&E. I was 13+4 weeks when we found out. The first couple weeks were extremely hard. Now that it's April I'm finding it hard again. I should be 19weeks and finding out the gender. Genetically he was fine. I'm just so lost. Our sweet baby boy. It's more of the why him? I've had 5 previous healthy pregnancies and births. Am I to old? Is my body failing? I was 34 when I lost him. Yesterday I turned 35 and I'm just scared I'll lose another.
