It may have been the triple screening..
Lol, sometimes, its so hard to understand my doctor,
because she's from .India, &has a very thick accent.
But she said that it's a bloodtest that tests for blood
abnormalities, &if they find anything abnormal,
they would do an amniocentisis..
[which scares the piss out of me, lol].
Of course it would probably be smart to have the test done.
Just in case.
