No love for my unborn child

I am a first time mom, planned pregnancy. I am having a hard time falling in love with my fetus. I have a few close friends that had babies with serious issues, including deformities, and I know that I could not handle that, so I would abort (husband agrees). Maybe I am worried that will be the case, so I'm hesitant to feel that overwhelming love other mothers feel for their babies until I know it's healthy. Can anyone else relate, or am I a heartless bitch?
