You most likely have a fungal / yeast (unprotected vaginal) or a bacterial infection. The best thing to try first is either clotrimazole (Canesten) cream or fluconazole tablets and you can get these from a chemist store ....
is it serious?
No, as long as you treat it correctly - long-term if you just left this the potential is it could develop into a severe, or even incurable skin condition. If these do not clear away within a week of trying the medication I mention, go and get medically checked or go to a Walk-In sexual health center .......
