Tiap malam akan rasa batuk

Aih, batuk malam je memang common during pregnancy, especially kalau uterus dah besar sikit, pressure kat chest dan amniotic fluid changes boleh trigger dry cough macam tu. Tapi since you're 18 weeks baru, baik check dengan doctor just to make sure bukan sign of something else like allergies or reflux yang pregnancy triggered (yang latter ni pulak memang suka jadi at night). Try minum warm water sebelum tidur and sleep with extra pillow to elevate, tapi definitely mention to your gynae at next visit, masa check-up saja pun takpa, takde perlu rush clinic.
