confused/angry

how come it seems that people who don't "deserve" children always come up pregnant but people who would make loving happy parents have a hard time getting prego? I work with a lady who completely downs my want for a baby but she she has a daughter but always complains about it and says if she could go back she wouldn't have her today? thats just so fn unfair. me and my hubby have been trying for a baby for about 2 months now, which I know isnt long enough to worry or get discouraged and that isn't what this is about but its like people out there try for years and years but dope heads, people who get their kids taken away and horrible people always seem to be the ones who can get pregnant even if they look at a baby it seems... I just think it's totally unfair.
