Has anyone ever heard of this? Has anyone had experience with it? Its basically a pool of blood near or in the placenta. I was in a car accident 2 days ago, and I went in for my OB check today and she found a placenta lake on my ultrasound. The doctor will call me tomorrow after he reviews it for further steps but I cant stop thinking the worst and stressing myself out. Has anyone had this and their pregnancy be fine? Im 19 weeks with my first baby girl, second baby.
