Jess - When i had my 12 weeks scan with this bub and also with Lily it was covered by medicare but i was out of pocket by $30. So all i had to pay was $30 on the day, then medicare sent me out a check for the rest which had to give to the u/s place. With the blood test, i didn't have it this time but with Lily it cost me nothing at all and was covered by medicare. I was told you can get it done between 11 weeks and 13weeks, 6days.
