I’ve been to my OB for ultrasounds and pelvic exams twice within the past few weeks on the 4th and 10th. Nothing is wrong with the baby but I still have brown discharge. On the 4th I went to the ER for vaginal bleeding(red) nothing was wrong and I went for a follow up on the 10th same result. But the brown discharge hasn’t stopped. What could be wrong. My cervix is 3.2 and the placenta is posterior. Should I go back to the ER?
