Sabar ya, kembung ni memang very common pada trimester pertama, hormon progesterone slows down your digestion, so it's totally normal at 10 weeks! My friend who was pregnant around the same time said her doctor advised her to eat in smaller, more frequent portions and chew slowly, which really helped reduce the bloating quite a lot. Do try to increase your fiber intake through fruits and vegetables, and drink plenty of water throughout the day. Also, it may help to avoid high-gas foods like kacang, kol, and carbonated drinks for now, as those tend to make the kembung worse. Semoga cepat lega and take care of yourself, dear!
