Thrush! 😭😭

Ok so I I've been in shone for days with a super sore lady area, crying in pain. Today I went to the GP Who told me I have thrush and a UTI. He prescribed canesten internal cream. I put it on around 6pm and if any things it's just got slightly worse 😭 I am so stressed and in pain and it's not good for me or my baby (I'm pregnant)

Anyone know how to make it ease off? Sudocrem, baby powder, canesten does NOT touch it.

Had anyone else tried canesten? Does it take longer than a few hours to work?
