Eh sayang, 4 weeks postpartum tu memang masih dalam periode penyembuhan, so tak heran ada sakit perut, bisa jadi contractions masih berlaku atau perut kembali normal. Tapi since you've already checked with the doctor dan dia kata takda yang serius, that's good lah, but kalau sakit tu terus-terusan or getting worse, jangan ragu pergi balik ok? A few of us mum friends pun pernah experience ni, sometimes it takes a few more weeks for everything to settle, especially if you're breastfeeding because that can trigger contractions jugak.
