Ay, mahirap sabihin talaga based sa description lang, pero if may sharp pain and then may discharge, kailangan mo talaga to confirm with your OB right away, especially since breech ka pa at 38 weeks na! One of my mum friends thought she lost her plug but it was something else, and good thing she went to the hospital agad para ma-check. Better safe than sorry, lalo na ngayon na malapit na due date mo, go to your clinic or birthing center na para ma-assess ng doctor kung ano talaga ang lumabas and kung okay lang ang baby.
