24 years old, TTC for 3 years

Hi everyone! Just looking for some conversation I guess... Husband and I have been TTC since August 2012 (1 month after our wedding) everyone I know is pregnant, has a baby, pregnant with another baby, or has been pregnant but terminated. I've never even had a real scare! I have a step daughter, she is 5. Her mother just had her third baby... It really gets me down in the dumps sometimes when I really think about it. Anyone else as frustrated as me?
