Pink discharge

Hello 

I was looking for some advice please. I stated with thrush symptoms so I used a Canesten pessary on Tuesday night. Yesterday evening I noticed some chalky discharge but some of it looked a little bit pink. Then today I noticed a small amount of blood (very small) in my underwear so im really worried.

today the itching is much better, but I have some mild feeling of irritation and burning inside after using the pessary. 

I’ve used them  before and never had bleeding. 

My last period ended on Monday and I’m on the combination pill.

thanks so much
