Down symdrome test yes or no?

When I do the test, i will be at week 11. Btw, im 37 yo. I feel that at my age, if do Oscar, result would be immediate to high risk, I likely would end up doing Nipt since Oscar result got false positive result. If doing both test, total will be 1.2k (nuh, private). Nipt 850, oscar 350. My opinion, u shd just go directly do Nipt. Ppl say those with 35 years and above shd just go for Nipt.
