I feel different

I had a miscarriage is sept at 9weeks and I am currently pregnant again at 5 weeks .... I was soooooo excited last time .... This time I find I am not emotionally attached yet .... I feel like I am waiting from the ok from the doctor that everything is ok .... I am gonna have an early ultrasound 6-7 weeks to make sure everything is ok. But with my first daughter I was overjoyed and now I feel like I am missing out because I can't share the news yet ... Just so confused ! And every feeling and such I am wondering if this is another miscarriage .... Any thoughts?
