Other Pregnant Women.

So I've been with my significant other for 9 years, he doesn't count high school years, so 5 years. We've been married for 2months. 
While we weren't married, I was on Mirena the entire time, because I always saw myself married when bringing a child into this world. (Nothing against the women who aren't married when they get pregnant, this is just what I've always wanted) 
Anyway, while we were dating, I didn't mind seeing everyone getting pregnant because I didn't want to be. I've been off of birth control for 4 months, but this is our second month trying, and nothing so far. 
Ever since we starting trying, I can't seem to be happy for anyone who IS pregnant. Well not everyone just those I feel don't really deserve deserve it. In example, my brother in law who doesn't have a job and lives at home with his mom. Or, a certain someone who was in the mist of separating then all of a sudden got pregnant. 
Is it bad that I'm feeling this way ? I really don't want to, but i feel like I can't help it.
