I started having a brownish pinkish discharge  about midday yesterday , the way you would right before a period or on the last day. Spoke to my OB this morning who said its old blood and I had nothing to worry about . Well now it's actual blood , it's not a lot , I only see it when I wipe but I'm terrified . I don't know whether to go to the ER , I've already gotten 2 vaginal ultrasounds so I'm afraid getting another one would hurt the fetus . I don't know what to do , has anyone experienced this , what do I do ?
