Im 24 years old and I seem to be bleeding lightly after already being on my period for more than a week, almost 2 now. Normally it lasts up to 3-4 days. The past 3 days its been a brownish-pink discharge. Now I was late about 5 weeks before I started, and now it seems to be neverending. Every now and then i will have cramps right below my panty line and my breast seem to be really sore, and never have been at times when I was on my period before, what could this be and should I be worried??
