i have thought ive got a yeast infection for a few weeks now but im too scared to say anything as im quite young and i feel as though i am overreacting. i usually get my period regularly but this month i havent got it yet and it is over 2 weeks late. i have been getting cottage cheese discharge and itching and burning. just now i felt down there and its very tight and theres a lump with little lumps on it and im really scared! do i need an operation? medication? or am i just overreacting??
