nervous...

I feel like I do not really have any pregnancy symptoms. I will be six weeks on Sunday. I had sore boobs and throw up twice. I am wicked moody tho but other than that since I found out over a week ago nothing. and now I'm worry. I don't want nothing to happen. my last pregnancy I was throwing up every morning from like 5 and a half weeks and on and was super tired. I don't have my Sono till the 7th of December. so I'm kind of freaking out
