Thrush since coming off the pill

Hi folks, 
About 3 months ago I came off the pill after the doctor told me "your cervix is a little red which is a side effect of the pill, but it's nothing to worry about" - I worried and came off but since I have had thrush each time I get my period... is this common and most importantly did it stop for you? 
This never happened to me before the pill but it's definitely changed something hormonally, I'm just hoping it's not permanent!
