Sakit di area rahim tu memang boleh jadi normal dekat stage ni, ligament stretching, Braxton Hicks contractions, atau baby positioning, tapi sebab it's been all day, better to check with your doctor or midwife just to be safe, especially to confirm baby's still doing fine (which is good sign dia masih gerak-gerak aktif!). A few of my mum friends kena macam ni juga towards the end and turned out okay, tapi everyone's different so don't self-diagnose lah. Call your clinic atau go for a quick check-up, derang boleh detect if it's something yang perlu attention or just the pregnancy discomfort kicking in!
