Thrush!!!

Hi ladies 1st Happy New Years to you all. I recently was dignosed with thrush and was given the 3 night treatment with the applicator. So finally plucked up the courage to do it after attending to him. So it gets done and I woke in morning and it seems like maybe I didn't do it cause it is all in my knickers and it's put me off. Is this normal or did I do it wrong please help I'd like to get my freak on again.
