Eh normal je tu, hun! Aku pun experience sama time first trimester, uterus sedang grow and adjust, so kadang terasa keras kejung especially pagi-pagi or bila dah lama dalam satu posisi. Tapi kalau disertai dengan bleeding, severe cramping, atau sakit yang tak hilang, better check with your gynae je to be safe, okay? A few of my mum friends said the same thing happened to them and it went away, tapi everyone's different so better get it confirmed. Jangan worry sangat, banyak normal things happen in early pregnancy yang boleh buat kita panic!
