yes, you can have a test result within 24-48 hours to check for DS ... with full results of other possibilities in two weeks - it is called a FISH test (cost extra) .... i did this as i could not wait another couple weeks not knowing. Did you have a 12wk scan ? ... was there any indication then ? .... if you can have the test now, at least you can prepare yourself if anything was to be wrong with bubs, the last couple weeks of pg are stressfull enough IMO ....
