feelings

I'm 13 weeks and 2 days and i don't know if it's just my hormones but I don't feel anything about being pregnant yet. When people ask me how do I feel and if I'm exiceted I feel nothing. But i want to be excited this is what I've always wanted and prayed for, even when I feel little flutters I smile but I want to be overly excited . I feel like a horrible mom 😔. Is this a temporary feeling?
