7 months of trying and getting no where

Anybody else starting to lose hope? I have had a baby previously with a different partner who passed away while I was pregnant, I never thought I would get to be in another loving wonderful relationship again with someone who is such a wonderful father to my son but I have been blessed... Now I'm struggling to fall pregnant again and we are both losing hope :( can anyone lift my spirits?? :( currently cycle day 3 with (sorry tmi) a crazy heavy flow
