Disconnected from Pregnancy

I feel so disconnected from my pregnancy. I will be entering my second trimester soon and it still doesn't feel real. The effects are real, considering I've been sick as a dog, but the warm fuzzy feelings aren't really there. I see everyone on here overjoyed and I'm a bit jealous. I don't know if I've just been so sick that I'm not able to enjoy it, or if I'm just genuinely not excited? I'm not upset at all about having a baby and I have an amazing husband beside me through it all. So, I don't know what my deal is. We both talk to my belly so that he or she will know our voices, but I just seems... I don't know. Not like I expected it to? I just feel so disconnected from our little one and I don't know how to connect with them. I'm afraid this is foreshadowing me potentially being a bad mother. What do I do...?
