15 weeks & bleeding

Tmi but please someone tell me if this is normal . It was followed by cramps and my doctor wont answer or reply . My doctors test me all the time for infections and all that so NO i do not

have anything .

UPDATE: Went in to the ER & they ran some tests & did an ultrasound , they told me i am bleeding in my uterus but tight now the bleeding is little . If it gets bigger i can lose the baby . If u guys have this problem go in asap an get checked
