3 months pp and I’m tired of this

Im 3 months post partum. And I have decided to get the iud as my birth control the paragaurd to be specific. And my vagina smells like if I’m on my period. I have bloody mucus discharge and I don’t know what to do. It’s stoping me from enjoying sex and having oral sex because I’m so insecure. Has anyone had this issue does it get better?
