Progesteron or cerclage?

For those that have been on progesterone vaginal suppositories, I'm wondering if they gave off a really foul odor in your discharge. For a while I've noticed a really foul odor and assumed it was the suppositories but now I'm starting to wonder if maybe I have an infection. I've never had such an odor come from my cervical mucus before so I just don't know.. The last time i went into the doctors about 3 weeks ago i was told i have Bacterial vaginosis, doctor said it could have been from anything. I have NOT been sexually active for 4 months now im 25w3d . i am a very clean person! i was told that i am high risk. And i also have a cerglage....

Could it be another BV? Is it from using the suppositories, or could my body just be irritated from the cerclage?
