Depressed a little long.

Not going to lie I look threw all of these post and see everyone that is pregnant. It depresses me because I want to hold a baby in my arms so bad. I love feeling them grow inside of me. This will be pregnancy number 3 if I can get pregnant. My last one was a still born and my first a miscarriage. I want to hear the patter of little feet running threw my house. My husband has two children from a previous marriage. I love them to death and treat them like my own. I just want to be able to see and hold and watch one of mine grow up. Can anyone give me ideas and what to do.
