Re: my odds of a downs baby are 1 in 113
Due to my age, my odds were 1/62 (without any tests). After the blood tests, they only raised to 1/73. I just had a level II ultrasound (at 17 weeks) and they couldn't find any abnormalities. I think the odds ratio that they give patients are terrible and don't tell you anything. You could be that 1 person or you have a 99% chance of having a normal baby. Go for the level 2ultrasound if you haven't had it already. I chose not to have the amnio and am praying for the best.
