vagina problems

i never had a problem about my vagina smelling . almost 2 years ago i had caught Chlamydia from my ex. (he aas the only one i was fucking for 2 years, he was out hoeing) i never had symptoms. got in a new relationship , got pregnant and kept getting yeast infections , i had gestational diabetes so i believe thats why i kept getting them . now im not pregnant and stuff my i feel like it stinks. i know diet can play a part . like what can i do ? exercise ? how much fruit and water a day ? my boyfriend says its fine but i know its not & i wanna fix it.
