BC giving me weird discharge ?

Every time I go on BC I get a thick white discharge kinda like yeast infection discharge but it doesn't smell and I don't have any other symptoms(itching, pain while urinating).. I've been on the pill and implant and I noticed getting that thick discharge while using both. It's about to be two weeks since I stopped taking my bc pills and the thick nasty discharge went away.. has this happened to anyone else ??
