May not belong here

Brooke
So I may not belong here because I do already have a child. I m so sorry if I offend anyone... but I'm not sure where to turn... I had my son almost 5 yrs ago and we have been trying for our second and every month same thing.. no pregnancy... I know I have had one and that I am incredibly blessed. But I also feel so lost and sad.. I have been to the dr they don't see any issues... should I go back and look at more testing? Please help I'm so lost and confused
