thrush symptoms 9dpo :(

Nicole
I'm on 9dpo and AF is due in 6 days and so far I've had very sore nipples and my mood swings have been amazing haha 
For the last 3 days I've had very red sore thrush like symptoms, I usually get a bit of soreness near my period but not as bad as this. Not sure if this could be an early pregnancy symptom with hormone change....?
