I used monistat 1 about two weeks ago. it took care of the yeast infection, but there is still white stuff when i have sex with my boyfriend.

Vaginal discharge?: If this is abnormal for you, see a doctor soon. Any new or unexplained vaginal discharge should be professionally evaluated. It could be an infection, including an STD, depending on your and your partner's sexual risks (new relationship, other partners recently, etc). It might turn out to be nothing important, but better safe than sorry, right?
