Aiyoo, week 14 and still vomiting macam first trimester lagi, memang boleh buat worried kan! A few of my mum friends jugak experience ni, some sampai second half of pregnancy lagi muntah, so technically boleh normal untuk some mummies, tapi kalau dah teruk and happening middle of the night like yours, better check with your doctor to make sure everything okay and maybe they can suggest something to help. Jangan worry sangat, tapi don't wait, go get it checked out, ya!
