Discharge normal in third trimester 35 weeks

Samantha

Every time I go to pee, not even 2 mins after I have this running out my vagina. I thought it’s pee when it frost happened but it’s not. I went to the hospital cause I had back pain lastnight told one of the doctor about this but he said it probably pee. When I told him it wasn’t but still didn’t believe me. They check my cervix still close. Has this ever happened to anyone. I see my OB on thrusday so I’ll let him know as well
