I've just had my second smear in 6 months as the first had 'minor minor discrepancies'.
I allowed 24 hours without using Vagifem or Ovestin.
As I had the test today I asked the nurse if HRT can affect results and she said yes. I Googled after and the recommendation seems to be 2-3 days gap before having the test.
Not one person either when booking or taking it has advised me of this. Is it a known thing?
