sound like you have a mixed infection - with candida (cottage cheese discharge) and bacteria ( greeny discharge) - you can go get over the counter vaginal suppositories and cremes to trate straight away.
Keep the area nice and clean - best thing is to carry a soda bottle around with you - with some camomile tea (yes!) in it - every time you use the bathroom - whilst urinating pour some camomile tea ( can be cold
not hot please) over the outside affected area - this way the urine won`t sting so much.
If it doesn`t get bertter within 3 days - go see a gynaecologist or your GP.
