Pregnant and freaking out; is this normal?!

Hello! I just found out we are pregnant, which came as a huge shock because I really didn't expect it to happen on the first cycle trying (family history of fertility issues). We wanted this and we are ready, we have a great income, own a house, have good jobs, are in our 30s, etc. But I can't help but panic, did we really want this NOW? Are we ready to change our whole lifestyle? I'm happy, but I don't feel that sense of intense joy that others probably feel. (I'm not a very emotional person to begin with though).

We literally just bought plane tickets to my best friend's wedding overseas when I will be at the 26 to 28(+4) mark. Will I have to stay home?

So many thoughts racing through my head and I kinda wish I waited to test in front of hubby, but he just left for a long day of work and I won't see him until night.
