NIPT/Harmony Scan

Hi

I have been thinking I would like to have the harmony scan (or similar, know there's several names) if there's a high risk on my 12 week scan tomorrow. I really don't feel like I want the more invasive tests they do on NHS.

I live in London.

Have any of you had it done, how was the experience?

Any recommendations on clinic?

Would I still need a scan, as well as the blood test, if I have just gotten the 12 week scan, or could I opt. out of it to (maybe) save some money?

How long for the results and what was the price?

Or is it just completely unnecessary?

Thanks all.
