Hai mama, yang ni memang biasa lah during pregnancy, terutama kalau da masuk trimester ketiga, hormon progesterone slow down your gut movement, jadi rasa nak berak2 tapi tak keluar apa. Since baby still tendang okay dan ko rasa fine je, probably constipation mixed with the stretching feeling je. Tapi kalau dah dua hari plus ada cramping yang really sakit or bleeding, better check dengan doktor ye, just to confirm everything is good, sometimes bab pattern change boleh jadi sign lain, so tak rugi nak dengar doktor je. In the meantime, minum plenty of water, makan fibrous stuff, jangan stress sangat, okay?
