Downs syndrome and age

I know the older you are the higher the chance is of having a baby with downs syndrome...

I'm 25 and my results came back as high risk (I had the combined test, bloods and neck measurements), has anyone else around this age come back high risk? And what was the outcome?All the doctors/nurses I have seen are really surprised

I'm just curious as it's a constant thought in my mind until my nipt test results come back next week.
