Went to the ER last night bc I was having THEE WORSE pain. I'm 19w + 5 they did an ultrasound and come to find out a piece of my placenta is lifted away from the rest (partially detached) HOW????? How does this happen and the doctor couldn't give me an answer. She says if there was bleeding she would worry but there's none. My question when I see my doctor tomorrow is what if the rest of the piece completely detaches?????
