Sayang, abdominal pain like that, especially if it feels like you need to pass urine, really needs a doctor's check as soon as you can, okay? At 35 weeks, better safe than sorry, so jangan tahan-tahan; go see your gynae or head to the clinic/hospital to get it sorted out properly. A few of us mums in my group had similar feelings dekat akhir pregnancy, but each case lain-lain, so doctor perlu check your baby and everything else. Jangan risau, could be many things, tapi kena confirm with the experts. Take care of yourself, and let us know you're okay!
