Okay so the doctor gave me some vagina gel to insert it with a syringe and I have read directions and she told me how to do it. And she said like a tampon but I never used a tampon don’t know how they work to put one in. ? That’s why I don’t use them now. Just wondering if anyone has had to get this it’s for when u keep getting bv for too much discharge naturally
