Oo normal yan, mama! A lot of us had colds and cough sa first trimester kasi our immune system is adjusting sa pregnancy, plus ang dami nang virus around. The thing is, kung tumatagal siya or may fever ka, better check with your OB para sure lang na okay lang ang baby at walang complications, kailangan natin malaman if kailangan ng safe medication para sa inyo, especially ngayon pa lang kayo sa early weeks. Stay hydrated and rest as much as you can!
