Embarrassing discharge

So before I got pregnant and had twins and had a copper iud put in so like 2 years ago lol I was also 126 and now am 200 but I've been experiencing discharge everyday and a weird smell. I never used to have this before I got pregnant never had a smell or discharge... Will this ever go away or does pregnancy ruin ur body forever lol And I have gone to my obgyn n I never have utis yeast infections or bv I miss being fresh
