How good can the odds be when you're 41?

[Squidwoman]

I'm booked in for the NT scan and blood test at the FMC next week and am considering my options if the risk is high.

BUT- how low could my risk be given my age (41) even if bloods and scan were good? I know my background risk is 1 in 80.

Is it likely I'm going to have to choose between CVS (risk but quick result) and Harmony (no risk but two week wait by which time it's too late for a surgical termination)?

Any advice appreciated....

The stats are useful rather than being 'shite'. They can help make a decision as to whether to seek further testing or not.

Not everyone wants to risk a mc by going direct to amnio/cvs.
