You know what? I wrote a post with the EXACT same title on her about a month ago!
No, you're not a bad person...I used to think I was, but then all the wonderful people on this forum reassured me that what I was feeling was completely normal.
When you're trying so hard to get pregnant, and someone falls pregnant by mistake and aren't even happy about it, it can be a real kick in the guts.
Personally, i've had several people fall pregnant around me since we've been trying and I just can't be happy for them...with time, i've accepted it and become a 'little bit' happy for them, but until i'm pregnant myself, I just can't be 'excited' for them.
Don't worry, you're NOT a bad, mean or cynical person, you're just a woman that wants a baby more than anything else in the world, and you just feel that its unfair that someone that didn't even plan for a baby is pregnant.
Chin up, your time will come and until then, we're all here for you
