This is my 3rd child my youngest will be 8 when the new baby comes. I can not figure this one out though. My others were the same and this one is so different. I throw up everything I want to eat strange things (combo of sweet and salty). Water makes me have heartburn and milk makes me sick but lemonade is like a drug lol. I'm only four weeks along and this baby is making itself known. My other two I wasn't even positive on my test until two to three months in and this one I didn't even need a missed period. It's so odd all I want to do is sleep and sleep.
