birth control

So I was on birth control in from may 2015- nov 2015 (6months) & the ENTIRE Time on birth control I was either spotting or bleeding heavy & i had a bad smell .I got off it b/c of that & after that, my period had been irregular(2x a month) every since, I get yeast infection a lot now (never had one before depovera) , my period will stop for months & I wasnt pregnant..I told my doctor but she said it's normal..has anyone else had similar things happen ? Because it's 2017 &I I'm still having problems
