So sad... Not sure how others deal

My husband is sound asleep. I am

laying here in tears... how does everyone cope? I can't help but think about it on a daily basis. He doesn't seem to understand and keeps saying he has no worries... that it will happen soon. He really has no clue how many people have issues despite being perfectly healthy. I don't want to constantly be the negative one but I can't help but feel so sad... especially with family constantly asking us when we are going to have children.... At the same time I get even more upset because he makes jokes about "knocking it out of the park" ...
