33, the new 35?

So there is NOTHING on the internet about 33 being the advanced maternal age for twins. zip, nada, zilch. and i have been looking.

since this is the first time i have heard that i was high risk for anything, i am (more) nervous. and a little mad. why would dr. OB schedule me for an ERA test and never tell me i was higher risk? and why not mention that i would be presented with the option for the CVS as an alternative? it would have been nice to have V there, or maybe more than 5 minutes in a stranger's office to decide.

let's just hope all comes out great with test. i may just keep my fingers crossed forever.
