I'm usually always irregular but it's starting to change a bit and I'm so confused. Okay so like 2 weeks ago I got this brown discharge in my knickers for 2 days straight (wasn't due my period for another 2 weeks at that stage) then it stopped and then my period came last night but was a week late and it was just brown it wasn't red it was just brown it was light enough and I don't seem to have any red blood in me? Does this mean anything? I'm 18 and about to start really hard exams so it could be stress but that's never happened before also sorry for the details haha
