Flagystatin vaginal ovules

Anyone prescribed flagystatin before? The pharmacist told me to insert with my finger. But it feels like the ovule doesn’t stay inside. After pushing it in vaginally, the ovule seems to slide outwards. It doesn’t come out of the vagina though. Just feel it sliding outwards as I remove my finger. Not sure if that will affect the effect of the medication. #infection #medication #vaginalinfection
