Eh, normal je lah bunda! Every pregnancy is so different, I was throwing up buckets by week 5 with my first two, tapi my third one I felt nothing until like week 8, so don't worry. Some pregnancies are just quieter, especially kalau your body dah kenal the drill from before. That said, since you're concerned, best to just mention it to your gynae at your next checkup, they'll do a scan and put your mind at ease straightaway. Congratulations on baby number three!
