Ahhh I understand your worry lah, takut hospital procedure kan, tapi honestly at 23 days postpartum with sudden clotting lagi, better safe than sorry jadi best you check with your doctor atau midwife sebab they need to make sure everything's healing properly, could be normal lochia tapi bisa juga something that needs attention. A few of my mum friends had delayed bleeding weeks after delivery and most turned out okay, tapi each person different, especially kalau previous bleeding was minimal je, so jangan risk lah, go get checked even if it's just a quick visit or call your clinic first nak tanya, better to put your mind at ease kan?
