to not trust the doppler?

[CarminaX]

Been admitted to hospital due to issues with the doppler. Gone from having high pi in all 3 samples with negative flow yesterday, 22mm liquor, to high pi in 2 samples, normal pi in one sample, and 79mm liquor today.

Not sure what this means and speaking to consultant tonight. They've been talking about inducing me etc based on yesterday's results, possible section. I'm now nervous that I'll end up with a section and early delivery based on unreliable results...

Anyone else had big discrepancies between scans which were close together?
