HELPPP

Hi, any mummies experience pain @ the lower abdomen (the pain feels like those whereby exercise after a full meal kind) throughout the entire night? I'm on week 23 currently. Had this pain last night about 1am and now 8am plus I'm still feeling this pain, but not as pain as 1am plus... anyone experienced this before and knows why? Will it affect my baby? asked kkh Dr before but the only thing she tell me is if in pain go kkh emergency ?
