Feeling Nervous

My husband and I have been TTC for years. We’ve been wanting a baby SO bad that it literally hurt and we were terrified it would never happen. Well, I’m 6 wks now and I’m not feeling as “happy” or “in love” as I always thought I would feel when I found out. I find myself constantly worrying that I’m just going to have a miscarriage, and I’m struggling to feel pregnant because I’m in denial that the pregnancy is going to go well. I feel terrible because I’ve been hoping and praying for this for so long and I just want to be excited. Is this somewhat normal? Should I try and calm down a little? Or do you think it will pass and it might just be the first trimester jitters messing with my emotions? I am so nervous I’m going to be a terrible mother if I don’t get my emotions figured out :(
