Sayang, at 17 weeks ada stretching of ligaments jadi rasa sakit tu quite normal lah, terutama kalau preggy second time sebab uterus dah pernah stretch sebelum ni, tapi kalau sakit tu severe, persistent, or ada bleeding/spotting, kena check with your doctor cepat-cepat ye. A few of us pregnant mums felt the same thing kat second pregnancy, rasa lebih obvious sikit, but everyone's different so better safe than sorry lah dengan your OB.
