First pregnancy-unexpected

Hi everyone, I just found out a few days ago that I am pregnant. My boyfriend and I weren't trying, but we also weren't preventing. I was tracking my cycle and being very careful around my fertile time. We both talked about the risk of using no protection and were okay if it happened. Now that it has, we are just both in shock. We both want kids and with each other, we just weren't expecting it so soon. I have so many mixed feelings, and I know it will take a while to fully set in, but I am truly terrified. We had a lot of plans to travel before we had kids, and now that's not totally an option. I am starting to get excited and he is too, I am just wondering if anyone else has been in the same situation and what you have done to make it sink in and be completely happy about it?
