We're Pregnant!!!!!

Ok, so I actually took the first pregnancy test on Saturday. I just couldn't believe it when two lines showed up. The pregnancy line was pretty faint though. Daley had just left to go work at his parents so I called him back home to show him. He was super excited too and gave me a great big hug!!!! Still though I was a little skeptical. I retested this morning. Still pregnant and the pregnancy line was even darker in fact it was just as dark as the default line. I will post pictures of the beautiful pregnancy test results later. So anyway I called the OB today. I am half way through my 4th week today (Wednesdays are the start of new weeks). My expected due date is March 11, 2009!!!! Ok so back up. I'll be honest. While I am super excited I am also a bundle of nerves. What if I am not a good mom? How can we afford a baby? What if I miscarry? All these nervous thoughts and questions are running through my head. My first two doctors appointments are August 1st and 22nd. We have decided to wait until the first trimester is over to tell anyone. ARG what a secret to keep. Also I find it disconcerting that while I know I am pregnant because two tests say so, I don't feel any different. Shouldn't I feel different? Could it mean that something is wrong? Should I have morning sickness at this point?
