So I went to a scan at 5 weeks due to bleeding and we could see the pregnancy sack and yolk sack, I then bled heavy when I was 6 weeks and went to er again and they done another scan however they could only see the pregnancy sack and yolk sack through an internal scan and I was diagnosed with a chronic hematoma, due to being so worked up I forgot to ask why they could see the sack at week 5 via ultrasound but only through internal scan at 6 weeks, I am going back in a week for growth comparison and have been getting all of the pregnancy symptoms still very strongly, can anyone help me out with how this is possible is it due to the haemorrhage?
