Niaxo's Trying To Conceive Wish

My husband and I have been trying to conceive for a year and a half now. I was pregnant recently but lost the child and we've been trying very very hard since then. I feel as though it will never happen and has discouraged me from wanting to keep trying. Every time I turn around, someone else is pregnant and not me! We want to start a family more than anything and I feel it's my fault it hasn't happened yet!
