Sayang, at 37 weeks dengan perut mengeras seharian + sakit sebelah kanan sampai pinggang, jangan tunggu, go to your clinic or hospital sekarang to get checked. Bukan nak takutkan, tapi at this stage better safe than sorry, especially since movement agak perlahan. Contraction atau Braxton Hicks normal la towards the end, tapi when it's combined dengan sakit yang persistent + movement changes, kena confirm dengan doctor. They'll do a quick check, fetal monitoring, examine perut, and put your mind at ease. First time mom jadi lebih nervous is totally normal, so just get yourself checked out, okay?
