hi, I'm 36 weeks pregnant, i had an appointment yesterday I'm not dilating but i think i might be losing my plug i had internal exams done and cultures taken & a sonogram because I've been having discharge the past week mucousy sometimes its a whitish to clear color but usually light brown or brown, but its a little red looking today and has blood in it, could that be from my exams yesterday? I'm worried should i call my dr or go the the emergency room? is it normal?
