Oh mummy, masa second pregnancy memang selalu lain sikit dengan first tau, tummy muscles dah pernah stretched before, so that pulling and tightening feeling tu boleh jadi more noticeable. Kalau rasa sakit or frequent sangat, mummy do check dengan doctor or gynae ye, just to make sure everything is okay and to get proper advice for your specific situation. Semoga mummy and baby sihat selalu!
