My 7th week of pregnancy

(I'm writing this but I won't post it until after we tell everyone. So if you stumble upon it after the fact don't think you missed it. I just want to have a record of what this pregnancy is like. I'd like this baby to have something different from Sophy.)
Ok, I've finished the 7th week of pregnancy. So I'm in the 8th week. I hate the way the count it according to the time you've completed not the time you're in. It makes it feel like a whole week has to pass before you get credit for it! Grrr! Anyway I still don't feel pregnant. I'm REALLY tired, but that is really it. It's so different from my pregnancy with Sophy. I was so sick all the time with her. I think that it must be a boy. My back is really hurting though. I went to the chiropracter today. It was nice. I go again on wednesday. I have my ultrasound on wednesday. After the ultrasound we'll finally know if everything is ok. I'm ready to know that everything is fine. Then we have the joy of telling everyone. Ok so here's what babycenter says about the baby right now:
How your baby's growing: Your baby still appears to have a small tail (actually, it's an extension of his tailbone), which will disappear in the next few weeks. But that's the only thing getting smaller. Now almost half an inch long — roughly the size of a raspberry — he has elbow joints and distinct, slightly webbed fingers and toes. In his oversized head, both hemispheres of his brain are developing. His teeth and the inside of his mouth are forming, and his ears continue to develop. Eyelid folds partially cover his tiny peepers, which already have some color, and the tip of that nose you'll be tweaking someday is emerging. His skin is paper-thin and his veins are clearly visible.Your little one also has an appendix and a pancreas, which will eventually produce the hormone insulin to aid in digestion. His liver is busy producing red blood cells, and a loop of your baby's growing intestines is bulging into his umbilical cord, which now has distinct blood vessels to carry oxygen and nutrients to and from his tiny body. You can't feel his gyrations yet, but your baby is like a little jumping bean, moving in fits and starts around his watery home.
