thick discharge, 3cm dilated

hello Mummies! i went for my checkup last 2 days & doc said that i was 2cm dilated alr @ nearly 38weeks. then on the same night, i had bloody stool + thick discharge which caused me worry so i went to KKH @ 3am only to be sent home despite being 3cm dilated as they mentioned its normal since im constipated. both bloody stool & thick discharge has been going on since then, up till today. may i know, if any mummies experienced the same, how many days after did your waterbag burst or you went into labour? please advise!🥺
