NIPT test results

So I’ve been anxiously waiting my NIPT results for two weeks now. I’ll be 12 weeks tomorrow and I’ll be 39 years old on Saturday. Got a call from OB this morning and there was an extremely low amount of fetal cells in my sample, much lower than was expected given I was almost ten weeks when sample was taken. Not enough to tell the gender even. They did however indicate that I am at high risk of having a baby with a chromosome abnormality. A 1 in 17 chance! She said depending on what type of abnormality that baby may not live long after birth. She even asked if I’d like to terminate the pregnancy! I of course said no, there’s still a chance that baby is perfectly fine. She also offered me an amniocentesis, but that carries a risk of miscarriage and since I’ve miscarried before, I also opted not to do this. She said we could do a series of three ultrasounds starting at 16 weeks, then 18, and 20 and could probably tell if there are any abnormalities, so I agreed to this option. I’m just beside myself with worry. I already have one special needs child and it’s a full time job parenting him. This has been a casebook pregnancy so far. I’ve had all the symptoms, my levels have been great, I’ve seen baby four times on ultrasound, last heart rate was 173. I wish I never would’ve had this test done. I guess I just looking for support, encouragement, and most of all prayers.
