Hi there it sounds as though you have got vaginal thrush. This can be cured quite easily using canestan cream/pessaries from the chemist . But see your doctor just to confirm this is the correct diagnosis. If you are sexually active then your partner can also get this and will have tiny red spots on his penis , penile discharge and white stuff that looks like cottage cheese under the foreskin. He may even have given it to you!!!
You both need to abstain from sex until it is cleared up completely.
hmmm it could possibly be just the vagina cleaning itself. It's a normal thing. BUT! it depends though. what exactly is it like? have you been sexually active? because there's a chance it could be an infection.
