should I be concerned??

Alley
I went in for my NT ultrasound and my ultrasound tech was very thorough on everything. Then she got to looking at my placenta and everything and got quiet very suddenly and she took like 6 pictures and labeled them sub chron hem. And then got back to the baby and was all happy and thorough again. The hemorrhage was measuring 4cm Long and 2cm wide. So should I be concerned or no. I'm 13 weeks 4 days
