Signs of Labor

Normal po ba na biglang sumasakit yung puson na parang nag dedismenorrhea for a few minutes, tpos babalik sya after a Few a minutes? Sign of labor na po ba sya? Tapos po white discharge na halos araw2 siya nangyayari. Konting discharge lang naman, parang patak patak. BTW i am 38 weeks and 4 days preggy.
