Alhamdulillah baby okay! 33 weeks pun dah boleh cakap agak mature na. Abdominal tightening + headache + vomiting tu memang boleh jadi warning signs (preeclampsia, contractions, etc), so you did the right thing rushing to hospital, CTG mungkin tak perfect sebab stress ke atau timing, tapi yang important baby okay la. Going forward, jaga makan regular-regular (every 3-4 hours), minum air banyak, and rest as much as you can, sometimes tight perut ni boleh triggered by dehydration or exhaustion. Tapi any time it happens again + pening kepala or sight changes, go straight to hospital jangan tunggu, okay? Better safe than sorry at 33 weeks. You're almost there!
