I've been having brown discharge since about tuesday, this is the third day in a row ive had it. 
I'm not sexually active nor have i had sexual contact, so we can rule an sti/std out totally.
It's not smelly, im in no pain at all, no soreness, throbbing. Only thing i can say is my urine feels warmer than normal. 
I have no history of any issues in the past other than thrush a couple of years ago, which was (i think) a side effect of a medicine i took. 
There were some illness bugs flying round the house last week...my brother had sickness and D. On the friday i was ill but i was only sick with a high temperature, which we had put down to sunstroke. 
i'm in good shape and i eat a healthy diet, i excercise, whether it be my job or some cardio. i dont drink any alcohol or smoke, nor have i (or will i ever) try drugs. 

anyone any ideas??
