Sayang, abdominal pain at 18 weeks boleh jadi normal (ligament stretching, baby growing), tapi kalau ada pressure on bladder area campur sakit, kena check dengan doctor cepat-cepat, terutama if ada bleeding, spotting, atau contraction-like pain. Better safe than sorry at this stage! A few of my mum friends had similar concerns around mid-pregnancy, and the doc put their minds at ease with a quick scan. Jangan tahan, pergi jumpa OB/GYN or go to hospital kalau sakit yang tak tertahankan ya.
