Bad Oscar result

Hi, I just received my Oscar result last week my ratio for ds is 1-21 and I’m 35 this year. My result is bad due to my blood test and age. Hcg 2.789 Papp 0.343 the result are quite different from my 1st pregnancy 6 years ago. Kinda worried and anxious. My gynae recommended us to go amniocentesis on my 16 weeks. Feeling so stressful. Keep googling and reading forum look for positive vibes. :(
