Eh, that sharp pain you're describing sounds like it could be lightning crotch, super common kat final weeks, especially kalau baby's head dah settling lower! Tapi sebab you're approaching labor time, better check with your doctor just to be safe ja, especially if the pain gets worse or other symptoms start showing up. One of my mum friends experienced the same thing around 37 weeks and doc said it was normal, but setiap pregnancy lain, so best confirm dengan your gynae ye!
