wlilian, big congrats. Yes that's a very common morning sickness most of us have. My last I also had that throughout 1st trime; just a nausea, didnt puke at all.
Pregnancy brings a whole new lot of changes doesnt it? The adverse food craving is normal too. And I kinda enjoy it as it's the time my hubby will cheong to satisfy my taste bud so long I say what I want to eat. Haa.
