Sti’s and contraception

Hi I had chlamydia a wee while ago and I got two check ups if I’m clear and it says I am but I’ve noticed I still have a bit of a smell down there. I was thinking could it possibly be from getting the rod and it messing up my body, last month I had my period 3 times with a few days gap in between. Anyone know why this could be happening I’m seeing a guy and don’t like having to worry about the smell and the amount of discharge I’ve been having, it’s like it’s extra moist down there all the time too, I would really like some answers and help please :)
