This is known as
vaginal discharge, we all get it to help clean up there. It is actually called candidas, and this is a bacteria that we all have to clean us, however, if we wash too much, wear tight clothing, or wash with perfumed products, we can get too much of it.
Also often we have more discharge when we are ovulating (approx 8 days after your period)
The best thing to do is contact your doctor, and they may prescribe you with canesten duo, which is just a cream and tablet to take.
