Sayang, ari-ari mencucuk tu memang boleh normal, especially bila baby dah growing and placenta dah attaching properly, tapi sebab ni involve placenta placement, better you check with your doctor or midwife to be safe, eh. A few of my mum friends pun pernah rasa benda yang sama, some normal jalan, but some kena monitor sikit je. Jangan risau, confirm dengan doktor lagi senang hati!
