Aiyoh sayang, 38 weeks dah, mmg normal lah rasa macam tu, yang mencucuk-mencucuk at the bottom tu is usually Braxton Hicks mixed with your pelvis stretching, and honestly the nervousness plus excitement will make it feel worse! A few of my mum friends who were also due around end Feb said they had the same, some went into actual labour around 38-39 weeks, others tunggu sampai due date or even over, every baby's own timeline lah. Since you're having sharp pains down there though, best to mention it to your doctor or midwife at your next checkup just to make sure everything's good, because at 38 weeks better safe to get checked out. Ganbatte, you're almost there!
