Mama, please see your doctor soon lah, day 30 pantang with heaviness around the uterus area, sore heels, and jahitan still not healed is worth checking out because sometimes ada complications yang perlu bantuan. Honestly, stress + kurang tidur + overdoing things with newborn boleh delay healing; a few mum friends I know went through the same and rasa better once they really rest and took it slower. Maybe ask your partner or family to tolong more with baby at night so you can sleep properly, recovery masa pantang tu kena prioritize jugak, bukan hanya jaga baby je.
