So, mine was like this in the beginning. They thought there were two sacs. One normal. One a bit abnormal. Both not showing baby or HB. What ended up happening was one was a bleed, and one was a sac. Which later showed a HB and baby. Either way. It looked just like this. I don't think it's a BO, because they usually have abnormally high numbers. Also. With ectopic, there are things called pseudosacs. They thought I might have that too. It's where the body produces what looks like sacs, but the baby is implanted in the tube. I kinda have a feeling it is a bit too early, and it's fine!
