Labor signs?

Hi mommies ftm here, advice naman po ng early labor signs. I’m in my 39th week, no mucus plug pero nagkakaron ako ng water discharge. Masakit din balakang and left legs, tumitigas tyan pero parang braxton hicks lang. Pero sobrang bigat ng puson na parang laging maiihi. Early sign na po ba ito? Need to know kasi nakakatakot manganak ng wala pang swabtest. 😫#1stimemom #advicepls #bantusharing #theasianparentph
