I woke up and saw brown discharge in my undies do I changed as soon as I put the new ones on right through them but its very little bit I tried a,tampon and,it came out dark no smell though I have not started and I'm 14 is this my period,or am I going to start in a,few days? If its not my period when will I start after the brown discharge.

It is really individual for each woman. Generally brown discharge is old blood being sloughed from the uterus. The confusing part is that it can come mid cycle. So long as it isn't accompanied by pain or cramping it is normal. Has your cycle stabilized or is everything still a little random?
