Just not excited

Hi everyone. This is my second pregnancy. My daughter I currently a year old. I’m due to start college in less than a month and currently 31 weeks pregnant. I’m just not at all excited. With my daughter, she was planned and I was so excited. This pregnancy was not planned (I had an iud). I’m also high risk due to my heart and several other complications with the placenta. I forget im even pregnant a lot of the time and when someone starts talking about him I just kinda hate the thought of having to go through the newborn phase all over again. I’m married and in a stable relationship. My husband is overjoyed and he can’t wait. I just feel like a terrible mother for feeling like this. Will it get better?
