mixed emotions about pregnancy

is it wrong that i feel like i should be more excited about my pregnancy? don’t get me wrong i am excited most of the time and i am looking forward to my child being here but there are other times where i just feel...indifferent about it all. it makes me feel so guilty because i know there are so many women who struggle with conceiving and it almost feels wrong that i’m not always over the moon about it all. opinions welcome please
