Am I awful for being spiteful of my best friend's pregnancy?

My best friends is pregnant and I feel very spiteful towards her. My husband & I tried to get pregnant for a couple of mos., but for medical reasons were not able to. Suddenly at the same time we were trying my friend becomes pregnant (supposedly unplanned on her part but I have my suspicions). I am not upset that she is pregnant & I'm not as I already have 1. But I am upset with her constantly bringing up her pregnancy like it is the best thing that has ever happened in this world. She has no money, but has made comments prior to pregnancy that she has friends & family that "wouldn't let the baby starve or anything". She also first started with "she didn't care if she got hand-me-downs" & now she is looking at $400 cribs & $200 crib beddings & strollers & stuff when there's perfectly good items that cost 1/2 that. What bothers me most is she does nothing (no job), but her friends will go out & buy this stuff because she always comes out "smelling like a rose".
