What the hell is going on?

I went in last Thursday for my first month check up with my IUD. she said I'm going very well everything, is normal.

I would say starting yesterday I have been bleeding and I have had a off odor. I dont know what it is or what's going on please help

I have had no itching,cramping anywhere, soreness,redness,no discharge, no irritation nothing of that sort just a light bleeding and off smell
