Sayang, senggugut atau pulling sensation tu quite common dalam pregnancy especially bila anak pertama, ligaments kita stretch and grow kan, jadi rasa macam cramps sikit is actually normal lah. A few of my mum friends had the same thing around that stage, yang important is kalau sakit tu severe, ada bleeding, atau terus menerus ja, better check dengan doctor cepat-cepat just to be safe and get peace of mind, especially lah since ni first baby you.
