Dreamer that is amazing news! What a terrible experience for you, but a great outcome.
I also think if you are worried about anything just get it seen to, and go to the best dr or sonographer you can afford, and if you don't like what they say get a second opinion.
The private u/s clinics pay heaps better than the hospitals so you typically get much better, more experienced operators at the private clinics. These little bundles will cost us a fortune over the years so may as well start emptying our pockets now!!
