Me too.. i am currently now in 7 weeks and i do not have morning symptom or giddiness so far. But i realised myself, i am now small eater, easily tired and encounter sore breast. My aunt told me that some women may get morning sickness in the 2nd trimester and some may not get at all.
I have read one article in the net, if we have lots of fats in our body, likely we won't easily got morning sickness or giddiness. True or false, i have no idea.
By the way.. Congrats to all mummies..
