I’m so confused? Did my baby move?? Which side did it implant?!

Okay so all of these were abdominal ultra sounds

First was 5wk 6days

Second was 6wk 6 days

Third is 9wk 4 days.....

The first two look like baby implanted on the left but now on my 9wk scan the yolk sac is on the right???

Anyone explain this to me please?

Thanks! X

To the comment saying things change... I didn’t even know it was possible lol! I thought whatever side it implanted it stayed that side! X
