I need to vent, get some closure...

I’m currently 9 weeks and 5 days pregnant. I’ve hardly had any pregnancy symptoms whatsoever other than the obvious missed period. I don’t even feel pregnant. I keep questioning if I’m even pregnant. I’m terrified to be excited because for some reason I just don’t feel like it’s possible, that there might not even be something in there. I’m also extremely terrified of having a missed miscarriage. I don’t go to the doctor till 12 weeks. Why do I fee this way? I’m pregnant, correct? (Like 10 positive test).
