is the odor musty or fishy?
any medical problems or medicines for you?
sounds like bacterial vaginosis, which is simply disruption of the vaginal flora which allows overgrowth of bacteria and/or yeast. This is caused by sex, pregnancy, douching, etc. Sounds like you may have a combination of the two. It may be an early yeast infection too. It's impossible for me to tell without doing an exam. If you notice thick white discharge (like cottage cheese) try over the counter anti fungal like Monistat.
what needs to be done is a weeks worth of antibiotics. You can wait until Monday if you're ok with that or go to an urgent care tonight and have an exam done.
what I am thinking is that you are seeing white discharge on the vaginal wall.
take your mirror and a q-tip and see if this is correct.
so this leans me towards the yeast infection.
dry white plaques on the vaginal wall can be a symptom of a yeast infection. Try the Monistat over the weekend and if things aren't improving by Monday call your doctor.
