Will it ever happen again....

I lost my baby boy Noah at 21 weeks in July 2015 due to severe hydrops. The doctors gave me all the options and said that he was suffering inside the womb and wouldnt survive past 30 weeks. So myself and my partner made the heartbreaking decision to end the pregnancy and Noahs suffering.
Its been 6 months since it happened and 3 of which weve been trying to conceive but nothing. I know its only been 3 months, which isnt long trying to concieve but after all the heartbreak and emptyness i think i just thought i would fall pregnant again immediately. I feel like now its just going to take months and months... Has anyone else been through the same thing and is there light at the end of the tunnel? X
