i think you will feel better once you can see and feel the baby moving inside you

You should talk to your doctor, this is not uncommon. What excited me most about being pregnant was imagining what the baby was going to look like.

What's with the picture of the baby in the womb with the gun, kinda creepy?

Well how far along are you? Have you felt your baby? because if not once you feel that baby move its more of a relization and you may get more excited.
Maybe you might be going through depression

Lady Bug, you are not a horrible person. It is common some mothers do not feel connected yet with their babies in the wombs.

I feel the same way. I guess it is because it is our first time, and we don't know what to expect. Especially in my early trimesters, I couldn't really feel that an amazing life-form is actually growing inside of me, it is just so subtle. But now as I get into my later trimester, I feel the baby move everyday, and it is so wonderful, and I start to feel my connection with the baby by feeling his movements.

I am sure things will get better later on for you.

I agree with daniclic. My sister had a baby in July and felt that because she didn't find out the sex, was why she felt so unattached to her baby. but as soon as that baby was born, you almost couldn't tear the baby out of her arms. She says now she couldn't imagine it any other way.
I think you're perfectly normal!
