Eh, this is actually quite common lah, some mums I know had zero morning sickness first trimester then it hit them like a truck in second trimester, so don't worry you're not alone! Tapi kalau dah teruk sangat muntah berulang-ulap dalam sehari, better you go see the KK doctor lah, because while it could just be the hormones ramping up, they need to check you're not dehydrated or anything else going on. In the meantime try nibbling on small things frequently instead of big meals, and keep sipping water or electrolyte drinks. Jangan tunggu kalau teruk, KK will see you fast anyway especially pregnant ladies, go get checked out, better safe than sorry!
Aiyoh, second trimester morning sickness can suddenly hit harder than first trimester for some mums, happened to a few of us too, so you're not alone! But since you're vomiting repeatedly throughout the day and it just started suddenly like this, it's safer to go to KK and get checked out rather than guess, especially if it's affecting your eating lah, because baby needs the nutrition. Could be the pregnancy hormones ramping up, or it could be something else like food poisoning or gastro, so better get the doctor to rule things out and give you proper help.
