Trying not to think about it..

Some days I can sit there and act like nothing has happened and others are the hardest days that I feel like the pain won't ever go away. On March 20th, 2018 I had my first misccariage as I am 19. My fiance and I have been trying for about 5 months now and I feel so discouraged after the loss. Feeling as if it were my fault. Needing a little advice on way to help cope. I trying talking to my mother but she didn't believe me.. I've been dealing with the pain, agony and guilt all myself. My fiance has been trying to help but I don't think he understand the extent of how I feel. I've been having baby fever and wanting a child for 2 years now. Does anybody have any advice? Anything is useful right now...
