L.H.
Some women do have near instant body changes and some don't. Everyone's different. I did. I became extremely tired for no reason at all. I could literally fall asleep on my feet when I was pregnant with my son. My mother-in-law said it's a very common symptom in China, which is how she knew I was definately pregnant before I even took the home test. The funny thing is the sleepiness only lasted around 2-3 weeks. Then a week or 2 later I got the morning sickness at various times of the day rather than just in the morning. I couldn't keep anything down except "red" food like things done up in tomato sauce, strawberries, cherries, sloppy joes, etc. Italian food was fine. Chinese food was a complete disaster. I'd get sick the minute I smelt cooked milk, fish cooking, and broccoli cooking. Hang in there. You might get lucky like me and have an easy delivery.
