Smelly white thick discharge out of nipple

I’m 6 months, I took my nipple piercings out at 4 months (no infection) but recently I’ve noticed my right nipple STINKS, I can smell it as soon as I remove my bra. I was messing around with it and this came out from where the piercing use to be, now whenever I squeeze it this comes. It smells like sour milk or a piercing that hasn’t been cleaned properly. I don’t think it’s an infection since I took antibiotics for a week a month or less ago for bv. I see my doctor in the middle of February so I’ll talk to her about it but this is concerning me.
