To Harmony or Not to Harmony?

El
Ok, so initially my doctor told DH and myself that the Harmony blood test is covered for all women due to a contract that they had. Well, turns out the contract expired and no one told him. He said that we could still do it, but we'd have to pay $250. The money isn't really the issue, I just don't know if I want to do it. I'm gonna love my little one no matter what. So, I'm asking for your opinions. Should I or shouldn't I get the test? Those of you who took the test, how long before results and how accurate? Thanks.
