Awww little love your pic, not great about your cyst though, they said the same to me when I had my scan, mine isn't massive but it's on the bigger side. But I had this with Henry as well and it disappeared on its own. Try not to worry to much, if they were really worried then they would want to check u sooner I would of thought.
Haley, thinking of you hun, hope it bypasses you without to much trauma, please let us know ur ok x x x
